(depuis C++11)
std::wstring_convert modèle de classe effectue des conversions entre std::string chaîne d'octets et std::basic_string<Elem> chaîne large, en utilisant un code individuel Codecvt conversion facette. std::wstring_convert assume la propriété de la facette de conversion, et ne peut pas utiliser une facette géré par une locale. Les facettes standards appropriés pour une utilisation avec std::wstring_convert sont std::codecvt_utf8 pour UTF-8/UCS2 et UTF-8/UCS4 conversions et std::codecvt_utf8_utf16 pour UTF-8/UTF-16 conversions .
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.
