`template< class Codecvt, class Elem = wchar_t, class Wide_alloc = std::allocator<Elem>, class Byte_alloc = std::allocator<char> > class wstring_convert;`		(seit C++11)

Vorlage Klasse std::wstring_convert führt Konvertierungen zwischen Byte-String std::string und Widestringfelder std::basic_string<Elem>, mit einem individuellen Code-Konvertierung Facette Codecvt. std::wstring_convert Eigentümerschaft übernimmt der Umwandlung Facette und können nicht eine Facette von einem Gebietsschema verwaltet. Die Standard-Facetten für den Einsatz mit std::wstring_convert sind std::codecvt_utf8 für UTF-8/UCS2 und UTF-8/UCS4 Umbauten und std::codecvt_utf8_utf16 für UTF-8/UTF-16 Konvertierungen .

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.
