I see you were using PCRE 7.9. Please re-check with the latest release,
8.11, which has the following change:
16. Added PCRE_ERROR_SHORTUTF8 to make it possible to distinguish
between a bad UTF-8 sequence and one that is incomplete when using
PCRE_PARTIAL_HARD.
There have also been other UTF-8 changes since 7.9.
