Macro Definition Documentation

U_ETHER

#define U_ETHER   ((char16_t)0xFFFF)

U_ETHER is used to represent character values for positions outside a range.

For example, transliterator uses this to represent characters outside the range contextStart..contextLimit-1. This allows explicit matching by rules and UnicodeSets of text outside a defined range.
