How do you make wierd symbols/letters like ⇒LïñЧå¥⇐ ?

some games don't allow weird symbols like that, maybe depending on your pc/laptop and what version it is, a lot of the writing/symbols changes. for some reason computers have different proccessing styles, so it explains why it won't work. sorry I can't help you with how symbols turn out, try alt+ __ (# or letters)
