      template< class Codecvt, class Elem = wchar_t, class Wide_alloc = std::allocator<Elem>, class Byte_alloc = std::allocator<char> > class wstring_convert;
      		 (desde C++11)
      std::wstring_convert modelo de classe executa conversões entre std::string cadeia de bytes e std::basic_string<Elem> cadeia de largura, usando um indivíduo código Codecvt faceta de conversão. std::wstring_convert assume a propriedade da faceta de conversão, e não pode usar uma faceta gerido por uma localidade. As facetas padrão adequados para uso com std::wstring_convert são std::codecvt_utf8 para UTF-8/UCS2 e UTF-8/UCS4 conversões e std::codecvt_utf8_utf16 para UTF-8/UTF-16 conversões.
      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.
