Hey @Kareimovich most likely the characters you’re using are special characters, and categorized as ‘emojis’ on Manychat (even though they’re not characters).
Could you try with latin characters (A-Z, a-z) to see if that works?
If so, I’d suggest you open a ticket with Manychat regarding characters support and show them your example.
This may be a Meta restriction, not a Manychat restriction.
