string in webclient class c# changed to uncorrect format

问题

I call my service in wcf as you can see :

  ClientRequest.Headers["Content-type"] = "application/json";
            string result = ClientRequest.DownloadString(ServiceHostName + "/NajaService.svc/GetCarData/" + plaque);

            var javascriptserializer = new JavaScriptSerializer();
            return javascriptserializer.Deserialize<NajaResult>(result);

But the returned data is like this :

{"CarColor":"آبي سير","CarModel":"1383","CarTip":"ال ايکس","CarType":"سواري","Chassis":"83844131","Family":"####","FuelType":1,"MotorNum":"12483068683","Name":"####","NationalCode":"0000000000","Plaque":"11-426د61","PlaqueCoded":110561426,"PlaqueType":"","SystemType":"سمند","VinNo":"IRFC831V3GJ844131"}

I converted it to UTF8 byte and again convert it to utf8 string but not solved.

The encoded data is in Persian language .

I traced the request in fiddler and i found that the data is come with the correct format as you can see ,But in my code is changed

The WebRequest contains the Encoding property you can set up before downloading the service reply. Details are here: https://msdn.microsoft.com/en-us/library/system.net.webclient.encoding(v=vs.110).aspx
