Thanks for the answers.
I think I'll duplicate the functions, one for ASCII (ANSISTRING) coding and
the other for UTF-8 (WIDESTRING). I think this is the best way.
But I've look for the description for UTF8Encode, UTF8Decode, UTF8ToAnsi and
UTF8ToUnicode in the documentation and I can't find it. What does they do?
