Receive POST data in non-UTF-8 encoding (ASP.NET MVC)

Question

my ASP.NET MVC Application is UTF-8, but I receive POST request in Encoding.Default from third-party app out of my control.

What is sanest and simplest way to change request encoding for only one action of one controller? (Rest of my application should remain UTF-8).

public class Message
{
 public int id { get; set; }
 public string phone { get; set; }
 public string mes { get; set; }
 public string to { get; set; }
}

[HttpPost]
public ActionResult Receive(Message msg)
{
        AddIncomingMessage(msg);
        return new EmptyResult();
}

You can do Action based request encoding in ASP.NET MVC with web.config location tag setting.

Sample web.config:

<configuration>
...
<location path="path/to/your/actionmethod">
    <system.web>
        <globalization requestEncoding="ISO-8859-1" responseEncoding="ISO-8859-1" />
    </system.web>
</location>
...
</configuration>
