What you really should do is convert things to wchar_t, and then
use functions that work with them (like wprintf()) to output
things.  This should be much more portable.

I find it unfortute libid3tag does everything with ucs4 instead
of wchar_t's.

Anyway, one problem you should probably be aware of is that
id3_ucs4_t is a long, which is typicaly 64 bit on a 64 bit
machine, and so is not 4 bytes as you might expect.

I'm not sure what's the best way to convert it from ucs4 to
wchar_t though, and can't think of a portable way, and I'd love
if someone could point me out how to do it.

(On Linux (glibc), casting it from a id3_ucs4_t to a wchar_t
seems to work, but it's not portable.)
