Classes
codecvt_utf8 (C++11)(deprecated in C++17)	converts between UTF-8 and UCS2/UCS4 (class template)
codecvt_utf16 (C++11)(deprecated in C++17)	converts between UTF-16 and UCS2/UCS4 (class template)
codecvt_utf8_utf16 (C++11)(deprecated in C++17)	converts between UTF-8 and UTF-16 (class template)
codecvt_mode (C++11)(deprecated in C++17)	tags to alter behavior of the standard codecvt facets (enum)
