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