title: Encoding issue on Chrome and not IE
body: <p>When creating an XDocument I get an XmlException with the following message:</p>
  
  <pre><code>system does not support 'iso-8859-1' encoding line 1, position 31
  </code></pre>
  
  <p>The first line of the Xml document looks like this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="iso-8859-1" standalone="yes"?&gt;
  </code></pre>
  
  <p>Here is the code I use to create the document:</p>
  
  <pre><code> xDoc = XDocument.Load(webResponse.GetResponseStream());
  </code></pre>
  
  <p>The weird thing is that the exception happens on Chrome and Firefox but not IE8.</p>
  
  <p>Any ideas?</p>
