grep/pcre2: fix an edge case concerning ascii patterns and UTF-8 data
If we attempt to grep non-ascii log message text with an ascii pattern, we
run into the following issue:
$ git log --color --author='.var.*Bjar' -1 origin/master | grep ^Author
grep: (standard input): binary file matches
So, to fix this teach the grep code to use PCRE2_UTF, as long as the log
output is encoded in UTF-8.
