Answer 1

for the hex2a provided by another user, it may not working if ascii code is over 128 (i.e text contains chinese , etc)

you can use the follow to return proper unicode

function hex2a(hex) {
    var str = '';
    for (var i = 0; i < hex.length; i += 2){

        var dec = parseInt(hex.substr(i, 2), 16);
        character = String.fromCharCode(dec);


        if (dec > 127)
            character = "%"+hex.substr(i,2);

        str += character;

    }

    return decodeURI(str);
}
