I am getting unexpected matches when using JIT, PCRE2_MATCH_INVALID_UTF and
PCRE2_PARTIAL_HARD.
This can be confirmed with pcre2test:

pcre2test.exe -pattern utf,match_invalid_utf,jit -subject partial_hard

PCRE2 version 10.35 2020-05-09
re> /\bch\b/
data> qchq
0: ch
data>

Wihout JIT there is no match:

pcre2test.exe -pattern utf,match_invalid_utf -subject partial_hard

PCRE2 version 10.35 2020-05-09
re> /\bch\b/
data> qchq
Partial match:
