WCF Exception: Text Message Encoding and ISO-8859-1 Encoding

Calling a webservice that uses ISO-8859-1 encoding from WCF

I am trying to consume an external Web Service (the web service has PHP implementation) using VS 2008, .net 3.5, WCF( Environment : Windows XP and VS 2008). I add Service Reference to Web Service, VS generates WCF Proxy.

Binding is basicHttpBinding.

I call to method in Web Service, using Proxy, then I started getting a ProtocolException, I received the following error message :

System.ServiceModel.ProtocolException: The content type text/xml; charset=ISO-8859-1 of the response message does not match the content type of the binding (text/xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly.

The first 644 bytes of the response were:

This was successful

Well, I needed to call a service in iso-8859-1 encoding.

Any useful sample source code for solve it?

Update:

The default encoder used in WCF only works with UTF-8 and UTF-16 (big and little endian).

If I use textEncoding="iso-8859-1" in binding in app.config,

I get this error:

System.ArgumentException: No se admite la codificación de texto 'iso-8859-1' usada en el formato de mensaje de texto. Nombre del parámetro: encoding.

Calling a webservice that uses ISO-8859-1 encoding from WCF

This MSDN page (http://msdn.microsoft.com/en-us/library/ms751486(v=VS.90).aspx) shows how to create a "CustomTextEncoder" which can support more than utf-8, utf-16 and unicode encodings. It includes full sample source code and was very useful for me to get things going.

I use CustomTextMessageEncodingElement, but I get error:

The content type text/xml; charset=ISO-8859-1 of the response message does not match the content type of the binding (text/xml;charset=iso-8859-1). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 1024 bytes of the response were:**

From code of Samples MSDN, I modify the constructor from CustomTextMessageEncoder class:

public CustomTextMessageEncoder(CustomTextMessageEncoderFactory factory)
{
    writerSettings = new XmlWriterSettings();
    writerSettings.Encoding = Encoding.GetEncoding(factory.CharSet);
    contentType = string.Format("{0};charset={1}", 
    factory.MediaType, this.writerSettings.Encoding.HeaderName);
}

I replace "{0};charset={1}" by "{0}; charset={1}" (I have included an blank)

Then, I get the error:

The message version of the outgoing message (Soap11 (http://schemas.xmlsoap.org/soap/envelope/) AddressingNone
(http://schemas.microsoft.com/ws/2005/05/addressing/none)) does not match that of the encoder

(Soap12 (http://www.w3.org/2003/05/soap-envelope) Addressing10 (http://www.w3.org/2005/08/addressing)).
Make sure the binding is configured with the same version as the message.

Fails for me, in TextEncoderDefaults.ValidateEncoding(Encoding encoding). System.ArgumentException: Not supports textencoding 'iso-8859-1'

You're right; I hadn't tested it before. Likely some stupid limitation in WCF.

Maybe better delete this answer.

Changing the implementation of CustomTextMessageBindingElement constructor sorted it for me public CustomTextMessageBindingElement() : this("ISO-8859-1") { }

I using UTF-8 and I still get this error. I searched my code for 8859 and VS does not find it. Yet another misleading error message!
