i can't add symbol in name

[yuyu]

i can added heart symbol in my display name but now i can't write any symbol
Is it now impossible to add any special symbols in the name?

Why did they take that feature down?

Names have to conform to unicode specifications now, since searching for a name with wingdings in it is impossible in game.
