interface UProperty

android.icu.lang.UProperty

Selection constants for Unicode properties.

These constants are used in functions like UCharacter.hasBinaryProperty(int) to select one of the Unicode properties.

The properties APIs are intended to reflect Unicode properties as defined in the Unicode Character Database (UCD) and Unicode Technical Reports (UTR).

For details about the properties see UAX #44: Unicode Character Database.

Important: If ICU is built with UCD files from Unicode versions below 3.2, then properties marked with "new" are not or not fully available. Check UCharacter.getUnicodeVersion() to be sure.

AND if NFC or NFKC, d) can never compose with a previous character. e) can never compose with a following character. f) can never change if another character is added. Example: a-breve might satisfy all but f, but if you add an ogonek it changes to a-ogonek + breve See also com.ibm.text.UCD.NFSkippable in the ICU4J repository, and icu/source/common/unormimp.h .
