Char32 t

Revision as of 11:25, 11 May 2015

C++ char32_t is guaranteed to never use less bits than char16_t and to be no less than 32 bits wide. This means that it can successfully store any UCS-4 character value.

Character literal must use single quotes preceding with the letter U (For example U'貓'). It is also possible to use octal or hexadecimal representation to produce literals.

char32_t is considered to be enumerable (thus you can use characters in constructs like switch).

Other C++ data types storing symbols

• char no less than 8 bits, one byte.
• char16_t no less than 16 bits, no less than char
• wchar_t whatever the largest block of addressable memory happens to be on the system
