... but as I walked down the road just after posting that, I realized
that I cannot make pcre_exec() do what you want. PCRE_ERROR_SHORTUTF8 is
given instead of PCRE_ERROR_BADUTF8, and both are generated during the
check for UTF-8 validity that occurs right at the start of pcre_exec(),
before it does any actual matching. Therefore, it does not have any
starting match value to put in the offsets.
