Class CJKWidthFilter

A TokenFilter that normalizes CJK width differences:

  • Folds fullwidth ASCII variants into the equivalent basic latin
  • Folds halfwidth Katakana variants into the equivalent kana

NOTE: this filter can be viewed as a (practical) subset of NFKC/NFKD Unicode normalization. See the normalization support in the ICU package for full normalization.
