The internal representation of a wchar_t is irrelevant as long as it can hold a code point; when you communicate with the outside world, you transform code points to/from a particular encoding, and there are dozens of them available. Trying to force wchar_t to use a particular encoding is pointless because it will inevitably be the wrong one and you'll need to transform it anyway. That said, UCS-4/UTF-32 (native endian) is the most obvious choice for an internal representation since it uses one fixed-width code unit per code point and therefore is the simplest to work with and to transform to/from, and UTF-8 is the most obvious choice for all other purposes.
