* Compatibility may change as platforms update their filtering. Always test in the target app first.

Why do some invisible characters get blocked?

Platforms actively filter out certain Unicode characters to prevent abuse (e.g., fake usernames, spam). As platforms update their systems, character compatibility can change. Always use our Copy-Paste Test tool to verify before committing.
