Okay, thanks for that.

I did some more checking and I realize now that the support is compiled in. 
Whether it is working or not, I am not sure (the locale setting, character encoding, 
and font also figure in).

I have read that more recent implementations of wchar_t can easily map to unicode
and that the regular C string functions work with multi-byte characters now. Will
have to do some more experimenting on this.

Cheers.
