Invisible Character

What is an invisible character?

An invisible character is a real text character that takes up no visible space, or only blank space, on the screen. The best known examples are the zero width space, the Hangul filler and the Braille pattern blank. Because they are valid Unicode characters, you can copy them like any other letter and paste them into chats, forms, documents and code.

Our invisible character tool gives you a ready list to copy with one click, shows the Unicode code point of each character and lets you repeat a character as many times as you need. It also includes a checker that finds and removes hidden characters from pasted text, which is useful when odd invisible symbols break your content. Everything runs in your browser, so your text is never uploaded.

Features of this invisible character copy and paste tool

• One-click copy: Copy any blank or invisible character and paste it straight into your app.
• Repeat count: Copy a character up to 100 times when you need a wider gap.
• Unicode code points: See the code point of every character, such as U+200B, so you know exactly what you are using.
• Hidden character detector: Paste text and see which invisible characters are hiding in it, marked in the preview.
• Safe cleaner: Remove hidden characters with one click, and keep the joiners that Urdu, Persian and Hindi text can need.
• Free and private: No signup, and nothing you paste is sent to a server.

List of invisible characters you can copy

These are the most useful blank and invisible characters. Some have no width at all, and some look like a space of a different size:

• Zero Width Space (U+200B): Has no width. It is often used to allow a line break inside a long word or web address.
• Zero Width Non-Joiner (U+200C): Stops two letters from joining. It is used in languages such as Persian and Urdu.
• Zero Width Joiner (U+200D): Joins characters together, for example in some emoji sequences and in scripts such as Hindi.
• Word Joiner (U+2060): Prevents a line break between two characters.
• Hangul Filler (U+3164): A blank letter from Korean script that many apps show as empty space. People often use it as a blank character.
• Braille Pattern Blank (U+2800): A Braille cell with no dots. It looks blank but still takes up width, which makes it popular for empty-looking text.
• Invisible Separator (U+2063): A separator meant for mathematical notation, with no visible appearance.
• No-Break Space (U+00A0): Looks like a normal space but does not allow a line break.

How are invisible characters used?

Invisible characters have many legitimate uses. Please follow the rules of the website or app you use, because many platforms limit blank names and messages, and never use them to mislead or impersonate anyone.

• Line breaks in long strings: A zero width space lets a long word or address wrap neatly on small screens.
• Spacing and layout: Blank characters can create gaps in a bio, a caption or a text-based design.
• Correct typography: Non-joiners and joiners control how letters connect in Persian, Urdu, Hindi and other scripts.
• Empty-looking fields: Where a platform allows it, a blank character can fill a field that must not be left empty.
• Testing software: Developers use invisible characters to check how forms, databases and search handle unusual input.

Why hidden characters cause problems

Invisible characters can sneak into your text when you copy from websites, PDF files or chat apps. You cannot see them, but software can. They can make two words that look identical fail a comparison, break search and replace, stop a code or password from being accepted, or add strange gaps inside a web address.

For SEO, a zero width space inside a title, a keyword or a URL can make it look different to search tools and crawlers. That is why it is a good habit to check text for hidden characters before you publish it or paste it into a content system.

How to remove invisible characters

Paste your text into the checker on this page. The tool lists every hidden character it finds, shows its Unicode code point and marks the exact place in a preview, for example as [U+200B]. Click the Remove button to delete them, then copy the cleaned text.

By default the tool keeps the zero width non-joiner and the zero width joiner, because languages such as Urdu, Persian and Hindi can need them to display words correctly. If you are sure you do not need them, untick that option and remove everything.

Tips for using invisible characters

• Test before you use: Paste the character into a test field first, because every app handles blank characters differently.
• Expect some apps to trim them: Some platforms remove or reject invisible characters, especially in usernames and messages.
• Keep them out of URLs and slugs: A hidden character in a web address can break the link or create a duplicate page.
• Think about accessibility: Screen readers may read blank characters in odd ways, so do not rely on them for important content.
• Keep joiners in Urdu and Persian text: Removing non-joiners can change how words are shaped and make them harder to read.
