UTF8 to/from wide char conversion in STL

Question

Is it possible to convert UTF8 string in a std::string to std::wstring and vice versa in a platform independent manner? In a Windows application I would use MultiByteToWideC

Answer 1

I don't think there's a portable way of doing this. C++ doesn't know the encoding of its multibyte characters.

As Chris suggested, your best bet is to play with codecvt.
