Summary

Enum values

Decomposition followed by composition.

Compose only contiguously.

Map, and reorder canonically.

"Fast C or D" form.

Enum values

COMPOSE

Added in API level 24
enum val COMPOSE : Normalizer2.Mode

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 https://www.unicode.org/reports/tr15/

COMPOSE_CONTIGUOUS

Added in API level 24
enum val COMPOSE_CONTIGUOUS : Normalizer2.Mode

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

DECOMPOSE

Added in API level 24
enum val DECOMPOSE : Normalizer2.Mode

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 https://www.unicode.org/reports/tr15/

FCD

Added in API level 24
enum val FCD : Normalizer2.Mode

"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.
