Webrequest og dansketegn

Hej

Jeg har denne funktion:

private string getUrl(string strUrl)
{
  HttpWebRequest request = (HttpWebRequest)WebRequest.Create(strUrl);
  request.Timeout = 5000;
  request.KeepAlive = false;
  WebResponse response = request.GetResponse();

  Stream ReceiveStream = response.GetResponseStream();

  System.Text.Encoding encode = System.Text.Encoding.GetEncoding("utf-8");

  StreamReader readStream = new StreamReader(ReceiveStream, encode);

    Char[] read = new Char[256];

    string strOut = "";

    int count = readStream.Read(read, 0, 256);
    while (count > 0)
    {
        String str = new String(read, 0, count);
        strOut += str;
        count = readStream.Read(read, 0, 256);
    }

    readStream.Close();
    response.Close();
    return strOut;
}

Mit problem er at giver jeg den en URL med æ, ø eller å så fejler den.

Nogle ideer til en løsning?
