Note that for some locales and for some code points, the application of Normalization
eectively removes distinctions.
Interestingly, dakuten- and handakuten-adorned kana are also subject to Normalization,
as is the distinction between half- and full-width katakana. ose adornments are consid-
ered to be accents in the context of Normalization.
ere are four types or levels of Normalization, as described in Table 3-94. e Normal-
ization that is applied to CJK Compatibility Ideographs takes place regardless of the Nor-
malization type. However, the Kangxi Radicals and CJK Radicals Supplement blocks are
subject to Normalization, but only for the NFKD and NFKC types.
