Here are the differences between the versions regarding use of PCRE2_UTF: o: opt->ignore_locale h: has_non_ascii(p->pattern) i: is_utf8_locale() l: !opt->ignore_case && (p->fixed || p->is_fixed) o h i l master hamza rene2 0 0 0 0 0 1 0 0 0 0 1 0 1 0 0 0 1 0 0 1 1 0 0 1 1 0 1 0 <== 7812.13, confirmed using fprint() debugging So http://public-inbox.org/git/0ea73e7a-6d43-e223-ab2e-24c684102856@xxxxxx/ should not have this breakage, because it doesn't enable PCRE2_UTF for literal patterns.
