Invisible Character

Some places reject empty text or collapse ordinary spaces. These Unicode characters look blank but are real characters. Copy one, paste it where you need it, and use the test area to check what you got.

How to use it

  1. Choose a character from the list.
  2. Press Copy this character.
  3. Paste it into the destination, or into the test area to see its code point.

Example

Pasting the Hangul Filler into a name field often gives a name that looks empty.

Questions

Is this allowed everywhere?

No. Many sites strip or reject these characters, and some treat them as spam. Use them only where the rules allow.

Which one should I use?

The zero-width space is invisible and has no width. The no-break space looks like a normal space but is not collapsed. The Hangul filler and Braille blank are wide, visible-width blanks.
