     * Escape characters that should not be included in a variable in a URL. It
     * is different to using URLEncoder.encode() because it escapes only what
     * is really needed to be escaped for modern browsers.
     *
     * Technically it is incorrect, but it makes for much nicer looking URL's
     * when working with non English languages.
     *
     * @param input
     *
     * @return The input string, with a limited set of special characters escaped.
