Non-ASCII character transfer between two asp.net MVC web applications will not be recognized

Question

I have two asp.net mvc-4 and mvc-5 web applications, now in my first asp.net mvc I have the following WebClientto call the action method (Home / CreateResource) in the second web application: -

using (WebClient wc = new WebClient()) 
         {
          var data = JsonConvert.SerializeObject(cr);             
          string url = scanningurl + "Home/CreateResource";
          Uri uri = new Uri(url);
          wc.Headers.Add(HttpRequestHeader.ContentType, "application/json");
          wc.Headers.Add("Authorization", token);
          output = wc.UploadString(uri, data);
         }

now inside the object datathat is passed to the second method of action, it contains a value for the password, and this value is equal in my case ££123, which has 2 non-ASCII characters ..

Now, according to the second method of action, he will take the above value as follows: -

- , , ASCII, ? , , . - , ?
