fix the special character filter (like "ñ")

now that the game is launched "globally" people who speak spanish are having trouble using any word in the chat that contains the "ñ" letter since the game blocks you from sending it

guess the portuguese and french people are having the same problem with the "ç" letter

and seriously i dont see whats wrong with using special characters for emoticons either so it seems like a dumb restriction anyways

While I don't personally use any special characters nor Japanese (which also gets deleted), but I agree that it should be fixed. Also, Alt + Enter to input a line break in chat also causes the chat to get deleted when trying to send.
