Re-visiting this, I don't understand your comment. You said your target string
was "+\001\177", but you did not say what length you gave to pcre_exec() [the
subject is specified as a pointer + length]. All three bytes in your string are
less than 0x80 (\200) and so will not be treated as starting a UTF-8 character.
I tried to reproduce any oddity using pcretest on the latest release, and in
all cases the return is just a match on the first "+" character.

What you submitted is NOT bad Unicode, or rather, it is not bad UTF-8; it's a
valid string of 3 single bytes (or 4 if you gave the length of 4).

I am going to close this report as "invalid". If there is further data that
might help me diagnose a problem, please re-open it.
