file.js

   s = s.replace(/\\n/g, "\\n")
            .replace(/\\'/g, "\\'")
            .replace(/\\"/g, '\\"')
            .replace(/\\&/g, "\\&")
            .replace(/\\r/g, "\\r")
            .replace(/\\t/g, "\\t")
            .replace(/\\b/g, "\\b")
            .replace(/\\f/g, "\\f");
        // remove non-printable and other non-valid JSON chars
        s = s.replace(/[\u0000-\u0019]+/g, "");
