Syntax
public class ICUNormalizer2FilterFactory : TokenFilterFactory, IMultiTermAwareComponent
Remarks

Supports the following attributes:

name A Unicode Normalization Form, one of 'nfc','nfkc', 'nfkc_cf'. Default is nfkc_cf.
mode Either 'compose' or 'decompose'. Default is compose. Use "decompose" with nfc or nfkc, to get nfd or nfkd, respectively.
filter A ICU4N.Text.UnicodeSet pattern. Codepoints outside the set are always left unchanged. Default is [] (the null set, no filtering).
