class wstring_convert;
(desde C++11)
std::wstring_convert clase de plantilla realiza conversiones entre std::string cadena de bytes y std::basic_string<Elem> cadena de ancho, utilizando un código de conversión individual Codecvt faceta. std::wstring_convert asume la propiedad de la faceta de conversión, y no se puede utilizar una faceta gestionado por una configuración regional. Las facetas estándar adecuados para su uso con std::wstring_convert son std::codecvt_utf8 para UTF-8/UCS2 y UTF-8/UCS4 conversiones y std::codecvt_utf8_utf16 para UTF-8/UTF-16 conversiones .
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.
