Invisible Character - Copy Blank Text (ㅤ) and Zero Width

What an invisible character is

An invisible character is a real Unicode character that draws nothing. Apps see it as text, so a name field that refuses to be empty accepts it, and a chat app that won't send a blank message sends it. You see nothing. That's the whole trick.

They fall into two groups. Blank characters take up space like a letter or a space: Hangul Filler (U+3164), Braille Pattern Blank (U+2800), em spaces and the no-break space. Zero-width characters take up no space at all: zero width space (U+200B), word joiner (U+2060) and the zero width joiners. Which one works depends entirely on how a given app cleans up input.

Which character to use where

Blank name or nickname (Discord, Steam, WhatsApp, games): start with Hangul Filler, U+3164. Most name fields strip normal spaces and zero-width characters, but many treat U+3164 as a letter. If it gets rejected, try Hangul Choseong Filler (U+115F) or Halfwidth Hangul Filler (U+FFA0). Games like Among Us and Free Fire have patched these in some versions, so it's a moving target.

Blank lines or spacing in an Instagram or TikTok bio: Braille Pattern Blank, U+2800. Instagram collapses repeated spaces and empty lines, but a line containing only U+2800 survives, which is how people get centered-looking bios and gaps between paragraphs in captions.

Empty message in WhatsApp or Telegram: Hangul Filler or Braille Blank. Breaking a long URL or word so it wraps: zero width space. Stopping a line break between two words: no-break space or word joiner. Aligning numbers in plain text: figure space, which is exactly as wide as a digit.

The detector: finding hidden characters

Invisible characters also cause real bugs. Code copied from a web page or a chat app sometimes carries a zero width space that breaks a variable name with no visible reason. A stray byte order mark (U+FEFF) at the start of a CSV file turns your first column header into something that looks like “name” but no longer matches it, and breaks imports. A no-break space in a password or an email address makes a login fail even though it looks identical.

Paste suspicious text into the detector box and it lists every hidden or unusual space character it finds, with its code point and count. Remove hidden characters and copy strips them out, turns no-break spaces into normal spaces and copies the clean text. Regular spaces, tabs and line breaks are left alone.

Be a good citizen

Blank names are harmless fun in a friend group. But zero-width characters are also used to dodge word filters, impersonate other users and hide tracking marks inside copied text. Many platforms treat that as a terms-of-service violation. Don't use invisible characters to evade bans or moderation.

They also have an accessibility cost. Screen readers may announce a blank name as “blank” or as the character's full name, and a bio full of Braille blanks can be read as a long list of “braille pattern blank”. Use a single blank where you need it, not dozens.

Why a character stopped working

Platforms update their input filters all the time, usually to fight spam and impersonation. A character that gave you a blank Discord name last year may now be trimmed or rejected. When that happens, work down the list: U+3164, then U+115F, U+FFA0 and U+2800. If all of them fail, the app has blocked blank names deliberately, and no character will get around it for long.

How to paste it correctly

Copy the character, then paste it into the field with Ctrl+V, Cmd+V or a long-press and Paste on a phone. Some apps trim a single blank, so set Copy how many to 2 or 3 and try again. On Instagram, type your bio in the app's own editor rather than pasting a whole block from Notes, because some keyboards convert or drop unusual characters. If you want a line to look empty in a bio, the line must contain only the blank character, with no regular spaces around it.
