         PCRE2_EXTRA_ALT_BSUX                 Extended alternate \u, \U, and
                                                \x handling
         PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL    Treat all invalid escapes as
                                                a literal following character
         PCRE2_EXTRA_ESCAPED_CR_IS_LF         Interpret \r as \n
