 （C++11 起）
类模板std::wstring_convert字节的字符串，std::string和宽字符串std::basic_string<Elem>之间进行转换，使用一个单独的代码转换方面Codecvt。 std::wstring_convert的所有权的转换方面，而不能使用的语言环境管理的一个方面。适合使用std::wstring_convert的标准方面是std::codecvt_utf8为UTF-8/UCS2和UTF-8/UCS4转换和std::codecvt_utf8_utf16UTF-8/UTF-16转换的.
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.
