A quiet ping, a joke or a gap in a group. The chat box often needs “something” before Send is enabled. A Unicode filler sometimes meets that requirement without showing a letter.
It may work depending on the app version and the field. iOS and Android do not always match. If it is rejected, try Hangul Filler or change the quantity.
Help
Rejected chats, messages that are not empty, and what to try.
The chat box may require visible content or trim Unicode it treats as empty.
You may see a box or an odd space. Try Braille Blank with a low quantity.
Copy 1 or 5 characters and send them to a test chat. If it fails, try Hangul Filler.

The generator is the starting point. The detector and guides help you see which character you are using.
