Invisible Character Generator

Unicode Invisible Character Generator - blank characters and zero-width

Unicode Invisible Character Generatorcreates and copies invisible characters to the clipboard: zero-width space, zero-width non-joiner, non-breaking space, invisible separator and others. Used for nicknames, blank messages, text formatting and advanced Unicode tricks.

What are the types of invisible Unicode characters?

Unicode defines many visually invisible characters:U+200B Zero Width Space (ZWSP)- invisible space, allows lines to be broken in place, does not take up visual space.U+200C Zero Width Non-Joiner (ZWNJ)- splits letters that would normally join (e.g. in Arabic/Persian).U+200D Zero Width Joiner (ZWJ)- combines characters (e.g. in emoji: 👨‍👩‍👦 = man + ZWJ + woman + ZWJ + boy).U+00A0 Non-Breaking Space (NBSP)- a space that does not allow lines to be broken between words.U+FEFF Byte Order Mark (BOM)/Zero Width No-Break Space- Historically, the BOM at the beginning of a UTF-8 file, also used as an invisible space.U+2060 Word Joiner- joins words (prevents breaking), but is invisible.U+180E Mongolian Vowel Separator- Has zero width on some systems.

Uses of invisible characters

Practical applications:Nicknaming- "empty" usernames in games (Fortnite, Among Us, Discord) by pasting ZWSP as a nickname.Empty messages- sending "empty" messages on Discord, WhatsApp via text composed only of ZWSP.Text separator- NBSP between number and unit (10 kg without line breaks: "10 kg").Digital marking- invisible ZWSP in documents to identify the source of a leak.Avoiding filters- inserting ZWSP inside keywords (not recommended, ethically problematic).Emoji combinations- ZWJ for creating complex emojis (family emojis, professions).

How to use invisible characters?

Method 1: Generator copies of the character to the clipboard (Ctrl+C) - paste anywhere. Method 2: HTML entity - for non-breaking space,​for zero-width space. Method 3: JavaScript -'\u200B'(ZWSP),'\u00A0'(NBSP). Method 4: copy directly from the page by selecting (the characters are there, although invisible). Check if the character works: paste into the text field and check the length -'​'.length(ZWSP) should be 1.

Detection and removal of invisible characters

Detection:/\u200B/gin regex - checks ZWSP. Comprehensive regex for all zero-width:/[\u200B-\u200D\u2060\uFEFF\u00AD]/g. Removing in JavaScript:str.replace(/[\u200B-\u200D\u2060\uFEFF\u00AD]/g, ''). Check in the editor: VS Code → Ctrl+H → enable regex → search\u200B→ highlights invisible characters. Security tools use ZWS/ZWJ detection to identify document tampering.
