Returns the last code point such that all those from start to there have the same value.
UCPMapValueFilter
uint32_t UCPMapValueFilter(const void *context, uint32_t value)
Callback function type: Modifies a map value.

ucpmap_get
U_CAPI uint32_t ucpmap_get(const UCPMap *map, UChar32 c)
Returns the value for a code point as stored in the map, with range checking.
UCPMap
struct UCPMap UCPMap
