Look in the serialization library. Robert Ramey peter@pgpnet.dk wrote:

Through google searches and examples I have found that using utf8_codecvt_facet from boost/program_options/detail/utf8_codecvt_facet.hpp allows me to imbue my std::wifstream like this:

std::wifstream f(p.string().c_str()); std::locale loc; std::locale utf8loc(loc, new boost::program_options::detail::utf8_codecvt_facet()); f.imbue(utf8loc);

and now the wifstream is able to read UTF-8 encoded files. However, I not been able to find any 'official' documentation of this feature, and I'm not really hooked on using undocumented features. Is there any documentation somewhere?
