This header was originally in the C standard library as <uchar.h>.

This header is part of the null-terminated multibyte strings library.

__STDC_UTF_16__
(C++11)
indicates that UTF-16 encoding is used by mbrtoc16 and c16rtomb
(macro constant)
__STDC_UTF_32__
(C++11)
indicates that UTF-32 encoding is used by mbrtoc32 and c32rtomb
(macro constant)
