Push Notification in non english languages

Question

I have implemented successfully this code:

Does anyone know how to write an Apple Push Notification Provider in C#?

It works great. But I have a question, can anybody help me how to send non english messages like Hebrew Or Arabic?

If the string contains any non english characters, it is not sent.

Thank you

I found the solution.

The length was wrong. In the code we pass the length of the string before the counting. We should count it after the UTF encoding:

writer.Write((byte)0); //First byte of payload length; (big-endian first byte) 
enter code herebyte[] b1 = System.Text.Encoding.UTF8.GetBytes(payload);
writer.Write((byte)b1.Length);     //payload length (big-endian second byte)
