title: Android GCM unicode charcters are not received
body: <p>This is my server side code or android side code.
  This code is working fine only for English messages. If I use Unicode charters like use Arabic language then it shows nothing in place of Arabic.
  In cause of English Arabic mix, it skip the only Arabic charters.</p>
  
  <p>Kindly give me solution.
  Thanks!</p>
  
  <p>This is my C# code</p>
  
  <pre><code>private string SendNotification(string authstring, string id, string msg)
      {
          try
          {
              ServicePointManager.ServerCertificateValidationCallback = (object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) =&gt; true;
              WebRequest request = WebRequest.Create("https://android.googleapis.com/gcm/send");
              request.Method = "POST";
              request.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
  
              request.Headers.Add(string.Format("Authorization: key={0}", authstring));
              string collaspeKey = Guid.NewGuid().ToString("n");
              string postData = string.Format("registration_id={0}&amp;data.payload={1}&amp;collapse_key={2}", id, msg, collaspeKey);
              byte[] byteArray = Encoding.UTF8.GetBytes(postData);
              request.ContentLength = byteArray.Length;
              Stream dataStream = request.GetRequestStream();
              dataStream.Write(byteArray, 0, byteArray.Length);
              dataStream.Close();
              WebResponse response = request.GetResponse();
              dataStream = response.GetResponseStream();
              StreamReader reader = new StreamReader(dataStream);
              string responseFromServer = reader.ReadToEnd();
              reader.Close();
              dataStream.Close();
              response.Close();
  
              return responseFromServer;
          }
          catch (Exception ex)
          {
              throw ex;
          }
      }
  </code></pre>
  
  <p>And this is my Android side code that catch the message.</p>
  
  <pre><code>@Override
  protected void onMessage(Context context, Intent intent) {        
      String message = ArabicUtilities.reshape(intent.getExtras().getString("payload"));
  }
  </code></pre>
