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

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

Macros
__STDC_UTF_16__	indicates that UTF-16 encoding is used by mbrtoc16 and c16rtomb (macro constant)
__STDC_UTF_32__	indicates that UTF-32 encoding is used by mbrtoc32 and c32rtomb (macro constant)
Types
mbstate_t	conversion state information necessary to iterate multibyte character strings (class)
size_t	unsigned integer type returned by the sizeof operator (typedef)
