My Below code is not working if I put one of the json field content as arabic.
Its working fine for english and other character.

RestClient client = new RestClient(myApiUrl);
RestRequest request = new RestRequest();
request.Method = Method.Post;
request.AddParameter("myJson", "{"statusName": "اسم الاختبار","description": "TestData"}");
request.AddFile("primaryFile", "C:\Testfile.txt");
RestResponse response = client.Execute(request, Method.Post);

I am expecting this code to be work with Arabic character in JSON Payload.

Thank you for any help
