Bug in Chilkat.HttpRequest Content-Length?

Hi.

I'm not sure what's the exactly problem here but I think it has something to do with the Encoding. I've used Firefox and the .NET Framework built-in HttpRequestMessage and both tell me that the Content-Length for this form data is 7 but Chilkat will make 9 out of it. Probably because of the "%20" space encoding. But if I send 9 to the server, he will reject the request.

 static void Main(string[] args)
    {
        // Set up some things
        const string logFileName = "log.txt";

        var url = new Uri("http://www.example.net/");

        var formData = new Dictionary<string, string>
        {
            ["space"] = " ",
        };

        // .NET Framework
        var request = new HttpRequestMessage(HttpMethod.Post, url)
        {
            Content = new FormUrlEncodedContent(formData)
        };

        File.AppendAllText(logFileName, $"Content-Length: {request.Content.Headers.ContentLength}");

        // Chilkat
        var http = new Http {SessionLogFilename = logFileName};
        http.UnlockComponent("test");

        var chilkatRequest = new HttpRequest
        {
            HttpVerb = "POST",
            ContentType= "application/x-www-form-urlencoded"
        };

        foreach (var pair in formData)
        {
            chilkatRequest.AddParam(pair.Key, pair.Value);
        }

        var response = http.SynchronousRequest(url.Host, 80, false, chilkatRequest);

        // See both results
        Process.Start(logFileName);
    }

Thanks in advance.
