The ISO/IEC 10646:2003 Unicode standard 4.0 says that:
"The width of wchar_t is compiler-specific and can be as small as
8 bits. Consequently, programs that need to be portable across any C
or C++ compiler should not use wchar_t for storing Unicode text. The
wchar_t type is intended for storing compiler-defined wide characters,
which may be Unicode characters in some compilers."
utf-8 is rather straightforward to handle and process.
