The size_t wcstombs(char *s, const wchar_t *pwcs, size_t n) looks like
the function i need, LC_CTYPE should be changed to tell the function i
would like the output in UTF-8.

However i failed to change LC_CTYPE. I tried setlocale(LC_CYTPE,
"en_US.utf8") and variants but none of them worked (MS VS2005). How
shell i do this?

(I am aware of function WideCharToMultiByte and it works fine but this
is an MS function, i would prefer a standard function.)
