My display name keeps getting removed for no reason,why?

[Demon Dismantled]

I have been trying to change my display name to ღ ღ  for the last two weeks, it gets accepted and suddenly 30 minutes later disappears and only a little heart is left on it, and there's nothing against the name, I'm currently wondering if this is just a glitch in the game or it is just against the rules to name yourself after the goddess of death? like somebody please help.. I've never had this problem before, why am I being penelyzed now?

most likely because the system doesn't like your choice of characters to write.

Better try a simple readable, or even standard and add just a little icon in it.

Please don't use special fonts for your display name or username.  They can be hard for others to read or pronounce, and as you have found, they can cause problems with the system.  Don't use special characters in group role titles, either.  That can prevent your being able to log in.
