Description Jakub Jelinek 2022-08-19 13:54:00 UTC 
localedata/unicode-gen/utf8_gen.py
lists the 6th element of JAMO_FINAL_SHORT_NAME as NI, but according to Unicode (all I've checked, Unicode claims names are immutable) it should be NJ.
See https://www.unicode.org/Public/4.1.0/ucd/Jamo.txt
11AC; NJ  # HANGUL JONGSEONG NIEUN-CIEUC
or
https://www.unicode.org/Public/14.0.0/ucd/Jamo.txt
11AC; NJ  # HANGUL JONGSEONG NIEUN-CIEUC

This means that UTF-8 contains entries like:
<UAD8D>     /xea/xb6/x8d HANGUL SYLLABLE GWEONI
that my Unicode name to codepoint function can't recognize, while
it can map "HANGUL SYLLABLE GWEONJ" to U+AD8D.
