How do I make a blank name?

Copy the Hangul filler (ㅤ, U+3164) and paste it as the name. Many games and apps accept it because it counts as a letter; if one says the name is empty or too short, paste it two or three times.

How do I send an empty message?

Use the braille blank (U+2800): it is a character, not a space, so chat apps don’t trim it and the message goes through looking empty.

What is a zero-width space?

U+200B: a character with no width at all, used to allow a line break inside a long word. Many sites remove it, so it is not a good blank name.

How can I find hidden characters in a text?

Paste it into Test here: every character is shown with its code, and the invisible ones are highlighted — useful when a copied password or a name “with nothing in it” behaves oddly.

Does an invisible character count toward a character limit?

Yes, one each: three Hangul fillers are 3 characters, like three letters. Test here shows the length both ways — in UTF-16 units, the way most “max characters” checks count, and in code points. An emoji such as 🦉 is 2 and 1.

How do I keep an empty line in a bio or caption?

Put the braille blank (U+2800) alone on the empty line. An app that removes empty lines finds a character there and leaves the line, while readers see nothing on it.

Is anything sent anywhere?

No. Copying and testing happen in your browser.

Invisible character

Blank characters to copy — for an empty name, an empty message or extra spaces.

How many to copy

Some apps trim spaces at the start and end — put the blank between visible letters, or use several.

Example

Example: an empty line that stays in a bio, and a gap in a game name

Two jobs for a blank. A bio should read “Bookworm”, an empty line, then “New York”, but the app squeezes out empty lines. And the name “Night Owl” has to go into a game that refuses spaces. Both are checked in Test here before pasting.

For the bio, copy the braille blank (U+2800) and paste it alone on the middle line. The line is no longer empty, so the gap stays.
For the name, copy the Hangul filler (U+3164) once, then type Night, paste it, and type Owl: 9 characters with a visible gap.
Paste each into Test here: every character is shown with its code, the hidden ones highlighted, and Length gives both counts.

Pasted into Test here	Length (UTF-16 · code points)	Hidden characters shown
Bookworm / ⠀ / New York (three lines)	19 · 19	LINE FEED, U+2800 BRAILLE PATTERN BLANK, LINE FEED, and the SPACE in New York
Night + Hangul filler + Owl	9 · 9	U+3164 HANGUL FILLER
Night + zero-width space + Owl	9 · 9	U+200B ZERO WIDTH SPACE, which leaves no gap at all
ㅤㅤㅤ (How many to copy: 3)	3 · 3	U+3164 HANGUL FILLER, three times
Owl 🦉	6 · 5	Only the SPACE; the owl emoji is 2 UTF-16 units

The blank line holds and the name shows its gap. Each blank counts as one character against a name limit, while an emoji such as 🦉 can count as two where the limit is checked in UTF-16 units.

How it works

Pick a blank: the Hangul filler (U+3164) is the usual one for blank names, the braille blank (U+2800) for empty messages and bios.
Set how many to copy and press Copy, then paste it where you need the blank.
If the app refuses it, try another one — or paste your text into Test here to see which invisible characters it contains.
