    		 (dal C++11)
    Modello std::wstring_convert classe esegue conversioni tra std::string stringa di byte e std::basic_string<Elem> stringa di larghezza, con un individuo di conversione Codecvt codice sfaccettatura. std::wstring_convert si assume la proprietà della faccetta di conversione, e non può usare un aspetto gestito da un locale. Le sfaccettature tipo utilizzabili con std::wstring_convert sono std::codecvt_utf8 per UTF-8/UCS2 e UTF-8/UCS4 conversioni e std::codecvt_utf8_utf16 per UTF-8/UTF-16 conversioni.
    Original:
    Class template std::wstring_convert performs conversions between byte string std::string and wide string std::basic_string<Elem>, using an individual code conversion facet Codecvt. std::wstring_convert assumes ownership of the conversion facet, and cannot use a facet managed by a locale. The standard facets suitable for use with std::wstring_convert are std::codecvt_utf8 for UTF-8/UCS2 and UTF-8/UCS4 conversions and std::codecvt_utf8_utf16 for UTF-8/UTF-16 conversions.
