         PCRE2_EXTRA_ASCII_BSD                \d remains ASCII in UCP mode
         PCRE2_EXTRA_ASCII_BSS                \s remains ASCII in UCP mode

       classes
                                                remain ASCII in UCP mode
         PCRE2_EXTRA_ASCII_POSIX              POSIX classes remain ASCII in
                                                UCP mode
         PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL    Treat all invalid escapes as
                                                a literal following character
