* Fix attempting to combine Hangul Jamo 0x11a7 0x11a7 is not a valid Hangul T syllable despite being equal to T_BASE. This is because, per the Unicode spec: TCount is set to one more than the number of trailing consonants relevant to the decomposition algorithm: (0x11C2 - 0x11A8 + 1) + 1 So the first valid Hangul T syllable is 0x11a8. Also see https://www.unicode.org/versions/Unicode17.0.0/core-spec/chapter-3/#G59434 for where the spec describes the usage of 0x11a8, not 0x11a7, during composition. * document that utf8proc_map simply wraps utf8proc_decompose and utf8proc_reencode (#312) * test code refactoring (#318) * Write regression test for #317 --------- Co-authored-by: Steven G.
