typedef uint16_t | UChar |

This file defines basic types and constants for utf.h to be platform-independent. umachine.h and utf.h are included into utypes.h to provide all the general definitions for ICU. All of these definitions used to be in utypes.h before the UTF-handling macros made this unmaintainable.

typedef int8_t UBool |
UChar |
Define UChar to be wchar_t if that is 16 bits wide; always assumed to be unsigned.
If wchar_t is not 16 bits wide, then define UChar to be uint16_t. This makes the definition of UChar platform-dependent but allows direct string type compatibility with platforms with 16-bit wchar_t types.
Definition at line 285 of file umachine.h.
typedef int32_t UChar32 |
Define UChar32 as a type for single Unicode code points.
UChar32 is a signed 32-bit integer (same as int32_t).
The Unicode code point range is 0..0x10ffff. All other values (negative or >=0x110000) are illegal as Unicode code points. They may be used as sentinel values to indicate "done", "error" or similar non-code point conditions.
Before ICU 2.4 (Jitterbug 2146), UChar32 was defined to be wchar_t if that is 32 bits wide (wchar_t may be signed or unsigned) or else to be uint32_t. That is, the definition of UChar32 was platform-dependent.
