In `unicodedata`, the functions `lookup` and `name` have some bugs and inconsistencies.

`lookup` matches case-insensitively, except for the algorithmic names of Hangul syllables and CJK unified ideographs, which must be in all caps. The documentation does not explain how character names are fuzzily matched.

`lookup` accepts names like “CJK UNIFIED IDEOGRAPH-04E00”, where the code point has a leading zero.

`lookup` and `name` don’t implement rule NR2, defined in chapter 4 of Unicode, for Tangut ideographs’ names.
