UTF-8 Javascript Encoding

Hope someone finds the code below useful...
I used to just use ascii but now I've changed to utf8 :-)

Code:

function URLEncode(string, encoding) {
    if (encoding == "ascii") {
        var i;
        var hex = "";
        for (i = 0; i < string.length; ++i) {
            hex += "%" + hexfromdec(string.charCodeAt(i));
        }
        return hex;
    } else {
        string = string.replace(/\r\n/g, "\n");
        var utftext = "";
        for (var n = 0; n < string.length; n++) {
            var c = string.charCodeAt(n);
            if (c < 128) {
                utftext += String.fromCharCode(c);
            } else if (c > 127 && c < 2048) {
                utftext += String.fromCharCode(c >> 6 | 192);
                utftext += String.fromCharCode(c & 63 | 128);
            } else {
                utftext += String.fromCharCode(c >> 12 | 224);
                utftext += String.fromCharCode(c >> 6 & 63 | 128);
                utftext += String.fromCharCode(c & 63 | 128);
            }
        }
        return escape(utftext);
    }
}

function URLDecode(encodedString, encoding) {
    if (encoding == "ascii") {
        var output = encodedString;
        var binVal, thisString;
        var myregexp = /(%[^%]{2})/;
        while ((match = myregexp.exec(output)) != null &&
        match.length > 1 && match[1] != "") {
            binVal = parseInt(match[1].substr(1), 16);
            thisString = String.fromCharCode(binVal);
            output = output.replace(match[1], thisString);
        }
        return output;
    } else {
        var string = "";
        var i = 0;
        var c = c1 = c2 = 0;
        while (i < encodedString.length) {
            c = encodedString.charCodeAt(i);
            if (c < 128) {
                string += String.fromCharCode(c);
                i++;
            } else if (c > 191 && c < 224) {
                c2 = encodedString.charCodeAt(i + 1);
                string += String.fromCharCode((c & 31) << 6 | c2 & 63);
                i += 2;
            } else {
                c2 = encodedString.charCodeAt(i + 1);
                c3 = encodedString.charCodeAt(i + 2);
                string += String.fromCharCode((c & 15) << 12 | (c2 & 63) << 6 | c3 & 63);
                i += 3;
            }
        }
        return unescape(string);
    }
}
