Invisible Character
Many apps refuse an empty field but will accept a character you cannot see. Copy one and paste it in.

How to use it
- Press Copy next to a character.
- Paste it into the test box to confirm that it counts.
- Paste it where you need it.
Good to know
Apps vary in what they allow. If one character is rejected, try another. Hangul Filler and Braille Blank tend to pass the most filters.
Please do not use them to impersonate someone or dodge moderation.
The six characters
| Character | Behaviour |
|---|---|
| U+3164 Hangul Filler | Blank with width, often accepted in names |
| U+2800 Braille Blank | An empty Braille cell, with width |
| U+200B Zero Width Space | No width, marks a place where text can wrap |
| U+2060 Word Joiner | No width, prevents a line break |
| U+00A0 No-Break Space | A normal-looking space that does not wrap |
| U+2003 Em Space | A wide space, useful for simple alignment |
Using the test box
Paste a character into the test box and watch the counter. If it goes up, the character was copied even though you cannot see anything. An app may still reject it, as many services filter these characters from usernames and messages. If one fails, try another from the list.
When invisible characters cause trouble
Zero-width characters picked up by copying can break passwords, code and search. If something that looks correct fails, retype it by hand. Please do not use these characters to get around moderation or to pretend to be someone else, which breaks the rules of most platforms.
Questions
