Yes, although I'd be much more interested in a string variant that could handle other multi-byte encodings too. That would be very useful, IMO.

Dinkumware has a commercial library which does conversions, based on the standard's codecvt mechanism, IIUC.
Fwiw, Metrowerks also ships UTF-8 codecvt facets, as well as other encodings (which is how Dinkumware packages this functionality). The Metrowerks version comes bundled with their std::lib. I'm not sure if other C++ vendors are doing this as well, but you might base a mulitbyte string on that assumption. The main stumbling block to portability would appear to be the name of the codecvt facets. For example our UTF-8 codecvt facet is spelled std::__utf_8<charT> where charT is normally a wchar_t, but could be a short or long (if you weren't happy with sizeof(wchar_t) for example). That is, our UTF-8 will adapt to a 16 or 32 bit wide character.
