Test: Pokémon
If you can type (or paste) it the forum software will handle it. Nowadays most things are Unicode enabled. That way I can carry my name with proper Polish letters in signature and have it display right.
I will try mine Slovak weird characters: áéíóúěľščťžýäôňľďĎŇŤČŠĽ, for example.
If it can handle ž, then it should be ok.
