Include Unihan variants in fuzzy search #31
Description
A semantically-based fuzzy search mode for ideographs as described in §2.1.6 (#24) should naturally also cover similar variants that are present in Unicode per se due to either application of the now deprecated source separation rule or a different component structure. These variants are discussed in Annex #38: https://www.unicode.org/reports/tr38/#N10211.
This can be implemented with the help of Unihan_Variants.txt: https://www.unicode.org/Public/17.0.0/ucd/Unihan.zip
The relevant subsets of Unihan variants are:
- kSemanticVariant
- kSimplifiedVariant
- kTraditionalVariant
- kZVariant
