MonoTouch - UIDevice.CurrentDevice.Name - UTF8

We noticed that UTF8 characters are not displayed correctly when used UIDevice.CurrentDevice.Name

in MonoTouch.

It comes out as "iPad 2 ??" if you use some special characters, for example, hold down the apostrop key on the iPad keyboard. (Sorry, I don't know the equivalent to show these symbols in windows)

Is there a recommended solution for getting the correct text? We don't mind converting to UTF8. I also tried to simulate this from a UITextField and it worked fine - no problem with UTF8.

The reason the problems are happening is because we are sending this text to the web service and causing problems with parsing the XML.

Here is the XmlWriter ( _parser.WriteRequest

) code snippet :

            using (XmlWriter xmlWriter = XmlWriter.Create(textWriter, new XmlWriterSettings 
                { 
#if DEBUG
                    Indent = true,
#else
                    Indent = false, NewLineHandling = NewLineHandling.None, 
#endif
                    OmitXmlDeclaration = true 
                }))
            {
                xmlWriter.WriteStartDocument();
                xmlWriter.WriteStartElement("REQUEST");
                xmlWriter.WriteAttributeString("TYPE", "EXAMPLE");
                xmlWriter.WriteEndElement();
                xmlWriter.WriteEndDocument();
            }

      

        
        
        
      

    

TextWriter is passed from:

public Response MakeRequest(Request request)
{
    var httpRequest = CreateRequest(request);

    WriteRequest(httpRequest.GetRequestStream(), request);

    using (var httpResponse = httpRequest.GetResponse() as HttpWebResponse)
    {
        using (var responseStream = httpResponse.GetResponseStream())
        {
            var response = new Response();
            ReadResponse(response, responseStream);
            return response;
        }
    }
}

private void WriteRequest(Stream requestStream, Request request)
{
    if (request.Type == null)
    {
        throw new InvalidOperationException("Request Type was null!");
    }

    if (_logger.Enabled)
    {
        var builder = new StringBuilder();
        using (var writer = new StringWriter(builder, CultureInfo.InvariantCulture))
        {
            _parser.WriteRequest(writer, request);
        }
        _logger.Log("REQUEST: " + builder.ToString());

        using (requestStream)
        {
            using (StreamWriter writer = new StreamWriter(requestStream))
            {
                writer.Write(builder.ToString());
            }
        }
    }
    else
    {
        using (requestStream)
        {
            using (StreamWriter writer = new StreamWriter(requestStream))
            {
                _parser.WriteRequest(writer, request);
            }
        }
    }
}

      

        
        
        
      

    

_logger

is recorded in Console.WriteLine

, it is turned on in mode #if DEBUG

. Request

is just a storage class with properties, sorry, easy to confuse with HttpWebRequest

.

I see??? in both XCode console and MonoDevelop console. I am also guessing that the server is receiving them strangely as well, since I am getting the error. Using UITextField.Text

with the same strange characters instead of a device description works fine without issue. This leads me to think the device description is the culprit.

EDIT: This has been fixed -

Encoding.UTF8.GetString (Encoding.ASCII.GetBytes(UIDevice.CurrentDevice.Name));
