Constants for normalization modes. For details about standard Unicode normalization forms and about the algorithms which are also used with custom mapping tables see http://www.unicode.org/unicode/reports/tr15/ ICU 4.4

Enumerator:
UNORM2_COMPOSE  Decomposition followed by composition. Same as standard NFC when using an "nfc" instance. Same as standard NFKC when using an "nfkc" instance. For details about standard Unicode normalization forms see http://www.unicode.org/unicode/reports/tr15/ ICU 4.4
UNORM2_DECOMPOSE  Map, and reorder canonically. Same as standard NFD when using an "nfc" instance. Same as standard NFKD when using an "nfkc" instance. For details about standard Unicode normalization forms see http://www.unicode.org/unicode/reports/tr15/ ICU 4.4
UNORM2_FCD  "Fast C or D" form. If a string is in this form, then further decomposition without reordering would yield the same form as DECOMPOSE. Text in "Fast C or D" form can be processed efficiently with data tables that are "canonically closed", that is, that provide equivalent data for equivalent text, without having to be fully normalized. Not a standard Unicode normalization form. Not a unique form: Different FCD strings can be canonically equivalent. For details see http://www.unicode.org/notes/tn5/#FCD ICU 4.4
UNORM2_COMPOSE_CONTIGUOUS  Compose only contiguously. Also known as "FCC" or "Fast C Contiguous". The result will often but not always be in NFC. The result will conform to FCD which is useful for processing. Not a standard Unicode normalization form. For details see http://www.unicode.org/notes/tn5/#FCC ICU 4.4
