Character name restrictions are client side, not server side

"Sorry non-alpha numberic....."

That error message you get when you type in special characters in your character name, is client sided. It does no server check. Im not a coder or anything, so I'm not sure how to fix that.

But since it is client sided, it would be a lot easier to repair this problem.

probably initially client sided then the server checks
but who knows, maybe you came across something (as to how to remove this check idk)
