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

Functions

mbrtoc8 (C23)	converts a narrow multibyte character to UTF-8 encoding (function)
c8rtomb (C23)	converts UTF-8 string to narrow multibyte encoding (function)
mbrtoc16 (C11)	converts a narrow multibyte character to UTF-16 encoding (function)
c16rtomb (C11)	converts a UTF-16 character to narrow multibyte encoding (function)
mbrtoc32 (C11)	converts a narrow multibyte character to UTF-32 encoding (function)
c32rtomb (C11)	converts a UTF-32 character to narrow multibyte encoding (function)

Types

mbstate_t (C95)	conversion state information necessary to iterate multibyte character strings (class)
char8_t (C23)	8-bit character type (typedef)
char16_t (C11)	16-bit character type (typedef)
char32_t (C11)	32-bit character type (typedef)
