 Well Regexp#escape don't do what you want ?

svg% ri Regexp#escape
--------------------------------------------------------- Regexp::escape
     Regexp.escape( aString ) -> aNewString
------------------------------------------------------------------------
     Escapes any characters that would have special meaning in a regular
     expression. For any string, Regexp.escape(str)=~str will be true.
        Regexp.escape('\\*?{}.')   #=> \\\\\*\?\{\}\.
