An “invisible name” is a name made of a blank Unicode character that takes up space but has no visible shape, so the name field looks empty.
Steps
- Open the invisible character tool and copy one.
- Paste it into the name or display-name field.
- If it shows up as a space or gets removed, try a different blank character.
Which character to use
Common options are the Hangul filler, a blank Braille pattern and the zero-width space. Apps treat them differently, so the best one depends on where you paste it.
Facts to verify: which invisible characters currently work on each game and app (record results in compat.json).
