an octal escape sequence, a special escape like C<\n> or a 3 or
more digit hex value.
+If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
+not a '\\'. This is because regexes very often contain backslashed
+sequences, whereas '%' is not a particularly common character in patterns.
+
Returns a pointer to the escaped text as held by dsv.
