header

<cuchar> (uchar.h)

Unicode characters

This header provides support for 16-bit and 32-bit characters, suitable to be encoded using UTF-16 and UTF-32.

Types

In C, this header defines two macros: char16_t and char32_t, which map to unsigned integral types of the appropriate size (the same as uint_least16_t and uint_least32_t, respectively).

In C++, char16_t and char32_t are fundamental types (and thus this header does not define such macros in C++).

Macros

In C++, the following macros are defined by this header:

Macro	description
`__STD_UTF_16__`	If defined, values of type `char16_t` have UTF-16 encoding. Otherwise, the encoding of `char16_t` is unspecified. (In C11, the macro expands to `1` when defined)
`__STD_UTF_32__`	If defined, values of type `char32_t` have UTF-32 encoding. Otherwise, the encoding of `char32_t` is unspecified. (In C11, the macro expands to `1` when defined)

Functions

c16rtomb: Convert 16-bit character to multibyte sequence (function)

c32rtomb: Convert 32-bit character to multibyte sequence (function)

mbrtoc16: Convert multibyte sequence to 16-bit character (function)

mbrtoc32: Convert multibyte sequence to 32-bit character (function)

Compatibility

This header, first introduced in C by a Technical Report extending C99, is fully supported by the latest standards of C and C++ (both published in 2011).
