Actually windows uses UTF-16, and I'm pretty sure OSX uses UTF-8 nativly.

I dont think you will need to do much manipulation of that kind.

Possibly, but I doubt it, the UNIX98 specification (later ISO/ANSI) for
the fw* functions is not that widly used, and the world seems to be
standardising on UTF-8. AFACR the Unicode people recommend UTF-8 as it
avoids endianess issues and is ASCII compatible.
