dfa: fix bug with ‘.’ and UTF-8 Hangul Syllables This fixes a bug introduced in 2019-12-18T05:41:27Z!eggert@cs.ucla.edu, an earlier patch that fixed dfa.c to not match invalid UTF-8. Unfortunately that patch had a couple of typos when dfa.c is matching against the regular expression ‘.’ (dot). One typo caused dfa.c to incorrectly reject the valid UTF-8 sequences (ED)(90-9F)(80-BF) corresponding to U+D400 through U+D7FF, which are some Hangul Syllables and Hangul Jamo Extended-B. The other typo caused dfa.c to incorrectly reject the valid sequences (F4)(88-8F)(80-BF)(80-BF) which correspond to U+108000 through U+10FFFF (Supplemental Private Use Area plane B). * lib/dfa.c (utf8_classes): Fix typos. * tests/test-dfa-match.sh: Test the fix.
