std::wbuffer_convert(3) C++ Standard Libary std::wbuffer_convert(3) NAME std::wbuffer_convert - std::wbuffer_convert Synopsis Defined in header <locale> template<class Codecvt, class Elem = wchar_t, (since C++11) class Tr = std::char_traits<Elem> > (dep- recated in C++17) class wbuffer_convert : public std::basic_streambuf<Elem, Tr> std::wbuffer_convert is a wrapper over stream buffer of type std::basic_streambuf<char> which gives it the appearance of std::basic_streambuf<Elem>. All I/O performed through std::wbuffer_convert undergoes character conversion as defined by the facet Codecvt. std::wbuffer_convert assumes ownership of the conversion facet, and cannot use a facet managed by a locale. The standard facets suitable for use with std::wbuffer_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. This class template makes the implicit character conversion func- tionality of std::basic_filebuf available for any std::basic_streambuf.
