I didn't test for special symbols, except for Euro Symbol (€), (and it's failed).

Also, I can't use some symbols with rendering issues as my nick name. œ becomes unnamed

Oddly, on Linux I can use € æ œ perfectly ingame! The majority of that utf8 text ingame fails to render though, even with as my screenshot shows Firefox can render every one of them.
