When UTF is enabled for a PCRE match, the corresponding flags are added to the pcre2_compile() call, but PCRE2_UCP wasn't included. This prevents extending the meaning of the character classes to include those new valid characters and therefore result in failed matches for expressions that rely on that extention, for ex: $ git grep -P '\bÆvar' Add PCRE2_UCP so that \w will include Æ and therefore \b could correctly match the beginning of that word.
