Character Counter

Character Counter Description

Introduction To Character Counters

In the digital age, where communication often takes place through electronic devices, the ability to measure and manage text length has become increasingly important. Whether you are writing a tweet, drafting an SMS, composing an email subject line, or creating content for websites and apps, understanding and controlling the number of characters in your text is essential. This is where character counters come into play.

A character counter is a simple yet powerful tool that counts the number of characters within a given text. Characters can include letters, numbers, spaces, punctuation marks, and special symbols. By providing an instant count, character counters help users ensure that their text fits specific length requirements or restrictions, improving clarity, readability, and adherence to guidelines.

The History of Character Counters

Character counters—tools that measure the number of characters typed in a text—are now ubiquitous in digital communication, helping users keep track of length restrictions for everything from tweets to SMS messages. While their presence seems almost trivial today, the concept of counting characters and the evolution of such counters has a fascinating history intertwined with the development of writing, printing, typewriters, and ultimately computers and the internet.

Early Beginnings: Counting Characters Before Digital Tools

The idea of counting characters, words, or letters has existed for centuries, long before the advent of computers. Ancient scribes and writers needed to measure texts for various reasons, such as maintaining the length of manuscripts, religious texts, or legal documents. Counting characters or words was a manual and tedious process but essential for tasks like copying, editing, and organizing large volumes of text.

For instance, ancient grammarians and scholars in places like Greece and Rome developed rudimentary ways to count letters and syllables, especially for poetry, where meter and structure were vital. The concept of “metrics” in poetry, measuring syllables and phonemes, can be seen as an early form of text quantification.

The Printing Press and Mechanized Counting

The invention of the printing press by Johannes Gutenberg in the 15th century revolutionized the written word. Printing introduced mass production of texts but also new challenges in layout, typesetting, and page design. Typesetters and printers had to manage space meticulously, often counting characters or words to fit text properly on a page.

Although no mechanical character counters existed then, the need to understand and control text length became more prominent. Printers developed manual tools like type gauges and grids to measure text and spacing, indirectly relating to character counting. The printing industry’s emphasis on precision laid the groundwork for automated systems that would emerge centuries later.

The Typewriter Era: Early Mechanical Counters

The late 19th and early 20th centuries saw the rise of the typewriter, the first widespread tool for mechanical writing. Typewriters standardized the process of typing characters onto paper, and typists often had to keep track of the number of characters for business letters, telegrams, and other communications limited by length.

Interestingly, some typewriters began incorporating rudimentary counters to keep track of the number of keystrokes or characters typed. These mechanical counters were often simple numeric dials attached to the typewriter, incrementing with each key pressed. Though not precise for all purposes, they helped typists monitor document length and billing in typing pools and offices.

One of the earliest examples of such a mechanical counter was the “typing meter,” a device designed to record the number of characters typed for billing or data collection purposes. However, these devices were not widely integrated into every typewriter and remained niche tools.

The Advent of Computers and Digital Counting

The development of electronic computers in the mid-20th century transformed character counting into an automated, instantaneous process. Early computers processed text as data and could easily count characters, words, and lines within digital documents.

In the 1960s and 1970s, text editing software and word processors emerged. Programs like IBM’s Electric Pencil and later WordStar and WordPerfect introduced character counting features to users, enabling them to track document length efficiently. These features were essential for writers, editors, and programmers working within storage and printing limits.

Unlike mechanical counters, digital counters could instantly provide exact character counts, including spaces, punctuation, and formatting codes. This precision was revolutionary and paved the way for many text-based applications that rely on strict length limitations.

Character Counters in Programming and Software Development

As computer programming evolved, counting characters became an essential task not just for writers but also for software developers. Programming languages often treat text as strings—sequences of characters that need to be measured, manipulated, or validated.

Functions to count characters appeared as basic utilities in programming languages such as C (strlen), Python (len), and JavaScript (.length property). These functions helped developers enforce input limits, process data, and manage memory allocation.

In addition, programming editors and integrated development environments (IDEs) included live character counters to assist developers in writing code, especially where line length or file size mattered.

The Rise of the Internet and Social Media: New Demands for Character Counting

The internet and social media era fundamentally changed the role and importance of character counters. Platforms like Twitter (launched in 2006) imposed strict character limits on posts—initially 140 characters—pushing users to craft concise messages. This led to the integration of live character counters within apps and websites to help users avoid exceeding limits.

Twitter’s character limit was inspired by SMS text messaging constraints, where messages were limited to 160 characters. Mobile phone manufacturers and network providers used character counters to bill and segment messages accordingly.

As social media platforms expanded, character counters evolved from simple numeric displays to interactive, user-friendly interfaces showing remaining characters, warnings, and even suggestions to shorten text.

Today, character counters are integrated into a wide array of digital tools: blogging platforms, email clients, messaging apps, and even online forms. They help ensure compliance with platform-specific limits and improve communication clarity.

Character Counters in Mobile Devices and Apps

With the proliferation of smartphones and mobile messaging apps, character counters became even more important. SMS messages retained their 160-character standard, and many messaging apps implemented counters to show how close a user was to this limit.

Beyond SMS, apps like Instagram, LinkedIn, and Facebook also implemented character limits on posts, comments, and bios, all supported by real-time character counting features.

Mobile keyboards and predictive text software sometimes incorporate character counting to help users gauge message length, especially in professional or public communication contexts.

Modern Innovations: AI, Accessibility, and Multilingual Counting

Character counters today continue to evolve, especially with advances in artificial intelligence and natural language processing. Modern counters can differentiate between types of characters, count emojis as single or multiple characters, and handle complex scripts like Chinese or Arabic more accurately.

Accessibility tools use character counting to help users with disabilities monitor their writing length or simplify text. Additionally, counters embedded in content management systems help SEO specialists optimize meta descriptions and titles within recommended length ranges.

Some modern counters also integrate sentiment analysis and readability scoring, expanding beyond mere character count to qualitative text assessment.

The Evolution of Character Counting Tools

Character counting tools, once a niche utility, have become integral to modern digital communication, content creation, programming, and data management. From simple manual tallies to sophisticated real-time counters embedded in platforms and software, the evolution of character counting reflects broader changes in how we communicate, compute, and consume content. This essay explores the trajectory of character counting tools—from their humble beginnings to their current sophisticated implementations—and examines their significance in diverse fields such as publishing, social media, education, coding, and SEO.

1. Early Manual Methods of Counting Characters

1.1 Writing and Word Limits in Print Era

Before the digital age, character or word limits were imposed manually in various writing contexts, such as telegrams, academic essays, and newspaper articles. Telegram services, for instance, charged by the word or character, necessitating a precise count. Writers and editors would often manually count characters or use physical templates to estimate lengths. These methods were time-consuming, error-prone, and often inefficient.

1.2 Typewriters and Character Control

With the advent of typewriters in the 19th century, a rudimentary form of character counting was introduced. While typewriters lacked built-in counters, page formatting and line limits were based on character counts, prompting typists to become highly aware of space constraints. Typewriter manufacturers standardized spacing and margins, which helped writers estimate character count per line, page, or section with reasonable accuracy.

2. The Digital Revolution and Early Software Solutions

2.1 Word Processors and Basic Count Functions

The rise of personal computers in the 1980s and 1990s brought about the first real automation in character counting. Word processing software like Microsoft Word, WordPerfect, and OpenOffice included simple character and word count tools. These counters were embedded within the document statistics and could provide quick feedback with a few clicks.

This marked a turning point: instead of manual or mental estimation, users could now instantly receive accurate counts for entire documents or selected text. While primitive by today's standards, these early digital counters were revolutionary in their accuracy and accessibility.

2.2 Programming and Text Editors

Character counting also became essential in the realm of computer programming. Languages like C, Python, and Java often require precision with string lengths, input/output limits, and data validation. Text editors like Notepad++, Sublime Text, and later Visual Studio Code began incorporating real-time counters to assist developers in debugging and formatting.

3. The Rise of the Internet and Content Optimization

3.1 SEO and Web Publishing

With the explosion of the internet in the late 1990s and early 2000s, character limits became vital in web publishing and search engine optimization (SEO). Meta descriptions, title tags, and snippet previews all required character-conscious editing. Tools like Yoast SEO and Moz integrated character counting into their platforms to guide webmasters in creating effective content within defined parameters.

Online content creators learned that exceeding character limits could lead to truncated search listings or reduced visibility. Thus, character counters became indispensable for ensuring optimal content performance in search engines.

3.2 Online Character Counting Tools

As the demand grew, standalone character counting websites emerged. These free tools allowed users to paste text into a box and receive not only character counts but also word counts, line counts, sentence length, keyword density, and other valuable metrics. Examples include platforms like:

CharacterCountOnline.com
WordCounter.net
Charcounter.com

These web-based tools expanded the audience for character counting from just professionals to everyday users—students, bloggers, marketers, and social media users alike.

4. Social Media and Character Constraints

4.1 Twitter and the Character Economy

One of the most significant events in the evolution of character counting tools was the launch of Twitter in 2006, which initially limited users to 140 characters per tweet. This constraint created a unique challenge: how to convey meaningful content in a highly restricted space. It wasn’t just about brevity—it became an art form.

To help users navigate these limits, Twitter integrated real-time character counters directly into its platform. As the user typed, the counter would update, changing colors to indicate when the limit was near or exceeded. In 2017, Twitter expanded the limit to 280 characters, but the embedded counter remained a critical user interface element.

4.2 Other Social Media Platforms

Other platforms also began enforcing character or word limits:

Instagram (2,200 characters per caption)
Facebook Ads (various limits on headlines, text, and descriptions)
LinkedIn Posts (3,000 characters max)
YouTube Titles and Descriptions

These platforms similarly included real-time counters or warnings, reinforcing the need for precise character management. In this era, character counting became a critical skill in social media marketing and engagement strategy.

5. Integrated Counters in Software and Apps

5.1 Content Management Systems (CMS)

Modern CMS platforms like WordPress, Wix, and Squarespace now come with built-in character or word counters, especially in SEO plugins and editor tools. Writers and editors rely on these features to ensure blog posts, meta descriptions, and titles meet platform requirements.

5.2 Messaging and Email Applications

Character counts also matter in messaging apps (e.g., SMS/MMS limits, Twitter DMs) and in email subject lines, where brevity can significantly impact open rates. Tools like Mailchimp and Campaign Monitor include character count checks to optimize subject lines and preview texts.

5.3 Mobile Apps and Development Tools

As mobile development advanced, character limitations became a factor in UI/UX design. Mobile app developers use IDEs (Integrated Development Environments) that highlight string lengths to avoid overflow issues or layout misalignments. Likewise, UI design tools such as Figma or Adobe XD often allow designers to simulate character overflow scenarios.

6. Advanced Analytical Tools and AI Integration

6.1 Smart Editing Tools

AI-powered writing tools like Grammarly, Jasper, ProWritingAid, and Hemingway Editor now incorporate advanced character and word counting. These platforms not only count but analyze sentence structure, passive voice, and readability—all while respecting content-length guidelines for specific use cases like academic writing, journalism, or copywriting.

6.2 Real-Time Feedback and Accessibility

Some tools now consider accessibility and inclusive design. For instance, they highlight where a message becomes too long to be easily readable or understandable, based on linguistic or cognitive load studies. Real-time counters are embedded within voice-to-text systems and adaptive technology platforms, supporting people with disabilities by guiding concise communication.

7. Character Counting in Programming and Data Science

7.1 Coding and String Manipulation

In programming, character counting is vital for:

Data validation (e.g., ensuring a username is ≤20 characters)
Security (e.g., password length enforcement)
File parsing and API communication (where payload limits exist)

Programming languages often include built-in methods such as .length() in Java or len() in Python to count characters. Developers use these functions in form validation, data cleaning, and performance optimization.

7.2 Natural Language Processing (NLP)

In NLP and machine learning, text analysis often begins with character and word counts. Tokenization processes depend on understanding the structure and length of input text. Language models (like GPT) have token limits—e.g., GPT-4 has a context window measured in tokens (~4-8 characters per token on average). Character counting helps manage input/output sizes for model efficiency.

8. Customization and API Integration

8.1 APIs and Automation

Character counting is now available as a service via APIs. For example, developers can integrate character counting functions into apps, CMS systems, or automated pipelines. These APIs often return counts along with additional metadata such as:

Sentence and paragraph count
Estimated reading time
Most common characters or words

Popular services include:

TextRazor
Aylien
OpenAI’s API (token-based counting)

8.2 Cross-Language and Unicode Considerations

As global communication expands, character counting must account for Unicode, emoji, and multibyte character sets (such as Chinese or Arabic). Some counters now differentiate between byte count and visible character count—critical for data storage, encoding, and internationalization.

9. The Future of Character Counting

9.1 Predictive and Contextual Tools

Looking ahead, character counting tools may become even more intelligent, factoring in tone, context, and target audience. A future tool might say not just “you’ve used 140 characters,” but “you’ve said too much for a tweet aimed at a teenage audience,” or “consider shortening for mobile readability.”

9.2 Integration with Wearable Tech and IoT

As wearable devices and smart interfaces evolve, concise communication will become increasingly essential. Devices with small screens—smartwatches, AR glasses—will demand brevity. Character counting tools could be embedded in these devices to help users stay within optimal limits.

How Character Counters Work

In today’s digital world, concise communication is critical. Whether you're crafting a tweet, filling out an online form, or coding a message in software, you’ve likely encountered a character counter — a small yet powerful tool that tells you how many characters you've typed. While it may seem trivial, the mechanics and significance behind character counters are more intricate and essential than many realize. This article explores what character counters are, how they work behind the scenes, their technical implementations, and why they matter in various contexts like social media, programming, UX/UI design, and data validation.

What Is a Character Counter?

A character counter is a digital utility, either standalone or embedded in applications, that counts and often limits the number of characters in a given text input field. It typically displays either the number of characters used, the number of characters remaining, or both.

For example:

Twitter limits posts to 280 characters.
SMS messages are traditionally capped at 160 characters.
Meta descriptions in SEO should ideally stay under 160 characters for optimal display in search engines.

These counters ensure input conforms to platform or system constraints, helping maintain data integrity, formatting consistency, or user engagement guidelines.

The Importance of Character Counters

Character counters serve both users and developers by:

Improving User Experience (UX): They guide users to stay within required limits, reducing frustration and ensuring that input is accepted without errors.
Ensuring Data Validity: On the backend, data is often stored in databases with strict field limits. Counters prevent overflow errors and ensure compliance.
Standardizing Communication: Especially in marketing, character counters help ensure uniformity in content presentation across platforms and devices.
Optimizing Performance: Shorter text inputs mean less storage and faster processing, which can be crucial for messaging systems and high-volume platforms.

Core Components of a Character Counter

To understand how character counters work, let’s break them into their fundamental components:

1. Text Input Field

This is the area where users type. It can be a <textarea>, an <input type="text">, or any similar component in a GUI (graphical user interface).

2. Event Listener

A real-time character counter usually listens for specific input events, such as:

keyup — triggered when the user releases a key
keydown — triggered when the user presses a key
input — triggered whenever input value changes, including pasting text

3. Counting Logic

The script attached to the event listener computes the length of the text by measuring the number of characters.

4. Output Display

The result is shown dynamically on the screen, either as:

“Characters used: X”
“Characters remaining: Y”
A progress bar
A percentage indicator

5. Limit Enforcer (optional)

Some character counters also block input when the limit is reached, either through browser-side scripting or backend validation.

How Character Counting Works Technically

JavaScript Example (Frontend)

Here’s a simple example of how a character counter works using HTML and JavaScript:

html

<!DOCTYPE html>
<html>
<head>
<title>Character Counter</title>
<style>
#counter {
font-weight: bold;
}
</style>
</head>
<body>

<textarea id="textInput" maxlength="280"></textarea>
<p>Characters remaining: <span id="counter">280</span></p>

textInput.addEventListener('input', () => {
const currentLength = textInput.value.length;
counter.textContent = maxLength - currentLength;
});
</script>

</body>
</html>

Explanation:

The <textarea> element is where users type their input.
maxlength ensures users can't type more than 280 characters.
JavaScript listens for input events and dynamically updates the #counter element with the remaining characters.

Character Count vs Byte Count

It’s important to distinguish character count from byte count:

Character count refers to the number of letters, numbers, symbols, and spaces.
Byte count measures the data size in memory, which can vary depending on encoding (e.g., UTF-8, UTF-16).

For example, the emoji 😊 may be one character but can take up 4 bytes in UTF-8 encoding. This becomes relevant in SMS, data storage, and transmission over networks.

Handling Special Characters and Unicode

Character counters must handle Unicode and special characters carefully, especially in multilingual or emoji-rich environments.

Challenges:

Combining characters: Some languages combine multiple code points into one visual character.
Emoji sequences: 👨‍👩‍👧‍👦 appears as one emoji but is actually composed of several characters.

Solutions:

Using JavaScript’s Array.from() or third-party libraries like GraphemeSplitter helps count visible characters (graphemes) accurately.

javascript

const text = '👨‍👩‍👧‍👦';
console.log(Array.from(text).length); // returns 1 instead of 7

Backend Validation

While frontend character counters improve UX, server-side validation is crucial for security and integrity. Input should be re-checked on the backend before storage or processing.

Example: PHP Character Limit Validation

php

if (strlen($_POST['message']) > 280) {
echo "Message too long!";
}

This ensures that users cannot bypass limits by manipulating frontend code.

Use Cases Across Industries

1. Social Media

Platforms like Twitter, Instagram, and TikTok impose strict limits to promote brevity. Character counters help users stay compliant while expressing themselves.

2. SEO & Marketing

Meta descriptions, titles, and ad copy often require exact character constraints for display and click-through optimization.

3. SMS & Messaging

SMS messages have 160-character limits per segment. Exceeding this can result in multipart messages or additional charges. Counters help users stay within limits.

4. Forms and Applications

Online forms for resumes, applications, and feedback often require concise entries, especially when parsed automatically by systems.

5. Programming and Development

In code editors, IDEs, and Git commit messages, character counters help enforce conventions and readability (e.g., max 72 characters for a commit title).

Comparison with Word Counters

In an increasingly digital world where communication, education, and content creation predominantly occur online, word counters have become indispensable tools. Whether embedded in writing platforms or available as standalone applications, word counters help users maintain clarity, conciseness, and structure in their work. Despite their apparent simplicity, different word counters function with varying degrees of accuracy, features, and user focus. This essay offers an in-depth comparison of word counters, exploring their types, features, advantages, limitations, and the scenarios best suited for their use.

1. Word Counters

A word counter is a digital tool that calculates the number of words and often characters, sentences, paragraphs, or pages in a given text. They are frequently used by:

Writers to meet publishing guidelines
Students to conform to academic word limits
Editors to assess readability
SEO professionals to optimize content
Translators and transcriptionists for billing based on word volume

Though seemingly uniform, word counters vary in their methodologies and outputs. Basic tools may simply count white space-separated tokens, while advanced ones account for syntax, language rules, or user preferences (e.g., whether to count numbers, hyphenated words, or contractions as one or two words).

2. Types of Word Counters

a) Built-In Word Counters

These are integrated into word processing programs like Microsoft Word, Google Docs, or Apple Pages. They offer immediate, real-time counts and usually display additional information like characters (with and without spaces), paragraphs, and pages.

b) Online Word Counters

Best Practices for Using Character Counters

Character counters have become an essential feature in digital tools, platforms, and interfaces where text input is limited. Whether you’re crafting a tweet, writing a meta description for SEO, or filling out an online form, character counters help ensure compliance with content constraints and enhance user experience. But how do you implement them effectively? This article outlines the best practices for using character counters in design, development, and content creation.

What Are Character Counters?

A character counter is a user interface element that displays the number of characters entered in a text field, typically in real time. They are particularly useful in contexts where there is a strict character limit, such as:

Twitter posts (280 characters)
SMS messages (160 characters)
Meta descriptions (up to ~160 characters for SEO)
Form fields (e.g., contact forms, feedback boxes)
Product descriptions in e-commerce platforms

Character counters can either show the total characters used, characters remaining, or both. They may also include visual indicators, such as color changes or progress bars, to make limits more intuitive.

Why Use Character Counters?

Before diving into best practices, it's important to understand the value character counters provide:

Improved Usability: They inform users of space limitations, reducing frustration and guesswork.
Error Prevention: By clearly indicating when a limit is exceeded, character counters help users avoid submission errors.
Accessibility and Clarity: Real-time feedback on character use ensures that users can make informed decisions about their input.
Better Content Optimization: Especially for marketers and SEO professionals, character counters help maintain ideal lengths for headlines, meta tags, and snippets.

Best Practices for Using Character Counters

Here are the top best practices to ensure your character counters are effective, user-friendly, and accessible.

1. Display Character Count in Real Time

The counter should update dynamically as the user types. Static counters or ones that only update after form submission are less helpful.

✅ Do: Show live updates like “75/160 characters” as the user types.
❌ Don’t: Wait until after submission to show that a limit was exceeded.

This provides immediate feedback, helping users adjust their input on the fly.

2. Use Clear, Intuitive Labels

Users should instantly understand what the counter means. Use clear labels such as:

“Characters used: 120/280”
“Characters remaining: 50”

If necessary, include a tooltip or help icon explaining the limit.

3. Use Visual Indicators

Color cues or progress bars add a layer of clarity, especially when approaching limits.

Green when within safe range
Yellow/orange when nearing limit
Red when limit is exceeded

Visual feedback helps users quickly assess how close they are to the limit without reading the exact number.

4. Warn Users Before They Reach the Limit

It's good UX to alert users when they're approaching the maximum.

Show a subtle color change or animation when they’re within 10-20% of the limit.
You can also provide suggestions like “You’re almost out of space—consider shortening your message.”

5. Allow Flexibility Where Possible

Hard limits can be frustrating. If the system can tolerate it, consider allowing slight overages or providing options like:

Auto-truncation (with user consent)
“Save as draft” even if limit is exceeded
“Shorten message” suggestions

For example, in social media scheduling tools, auto-shortening links or trimming text with ellipses might help users stay within limits.

6. Ensure Accessibility

Character counters should be accessible to all users, including those using screen readers or other assistive technologies.

Use ARIA attributes to announce character limits and updates.
Provide textual cues, not just color changes.
Make sure counters are navigable via keyboard.

For example: Use aria-live="polite" to announce changes in character count.

7. Position Counters Strategically

The location of your counter matters. The most common, user-friendly placements include:

Bottom right or bottom left of the input field
Inline with the input (for short fields)
At the top or side for longer content like blog posts

Avoid placing it too far from the input field, as this can confuse users.

8. Consider Mobile Users

Ensure your character counter is responsive and easy to read on smaller screens.

Use scalable fonts
Avoid crowding the input area
Place counters where they don’t obstruct text input

Touch targets should be appropriately sized for interacting with help icons or expandable counters.

9. Match Platform-Specific Requirements

If you’re building a multi-platform tool (e.g., a social media scheduler), tailor character counters to platform-specific rules.

For example:

Twitter counts links and images differently than regular text
SMS may split messages after 160 characters (70 for Unicode)

Offer smart counters that adapt based on content and context.

10. Provide Feedback on Overages

Don’t just stop users from typing; give them feedback and guidance:

Explain why input is too long
Suggest trimming or rephrasing
Highlight the portion that exceeds the limit

Avoid sudden cutoffs that could result in lost work or confusion.

11. Support Copy/Paste and Undo

Users may paste large chunks of text or accidentally delete content. Ensure your character counter supports these actions:

Accurately recalculate after paste or cut
Update in real time after undo/redo

This minimizes frustration and improves reliability.

12. Customize for Different Use Cases

Different applications require different styles of character counters. Examples:

Forms: Simple numeric counters like “50/100”
SEO tools: Include recommendations like “Best length: 150–160 characters”
Messaging apps: May include message segment counters (e.g., “1/2 SMS”)

Tailor the design to the context for maximum effectiveness.

Common Mistakes to Avoid

Even with best intentions, poorly implemented character counters can hurt usability. Avoid these pitfalls:

Not displaying the counter until a user types: It’s better to show the limit from the start.
Using only color for warnings: Not everyone can perceive color changes. Use icons or text as well.
Hard-truncating user input without consent: This can cause confusion and data loss.
Counter not accounting for special characters: Some platforms treat emojis, links, or HTML entities differently.
Overly aggressive enforcement: Rejecting a form for one extra character can be frustrating.

Real-World Examples

Here are a few examples of effective character counters:

Twitter: Uses a circle progress indicator that turns orange and then red when the limit is exceeded.
Instagram bio editor: Shows “147/150” live and won’t allow saving if you exceed.
Google Ads: Provides live feedback and optimal character ranges for ad copy, with helpful guidelines.
LinkedIn: Shows both a counter and a progress bar when editing headlines or summaries.

Conclusion

Character counters are small UI elements that play a big role in enhancing digital interactions. When implemented well, they improve usability, guide content creation, prevent errors, and support accessibility. Whether you're designing a form, a mobile app, or a content editor, following the best practices outlined here ensures your character counters are helpful rather than hindering.
