title: XML invalid Character !.
body: <p>I have been getting an invalid character! on what looks like the £ sign in the xml i am processing. I get "Invalid character in the given encoding." here is a code &amp; xml snippet.</p>
  
  <pre><code>&lt;outputs&gt;
  &lt;output id='1'&gt;
  &lt;key&gt;&lt;![CDATA[123]]&gt;&lt;/key&gt;
  &lt;message id='84'&gt;
  &lt;source&gt;&lt;![CDATA[123]]&gt;&lt;/source&gt;
  &lt;sender&gt;&lt;![CDATA[Paul]]&gt;&lt;/sender&gt;
  &lt;text&gt;&lt;![CDATA[Testing Currency £7.50 $9.999 _]]&gt;&lt;/text&gt;
  &lt;/message&gt;
  &lt;/output&gt;
  &lt;/outputs&gt;
  </code></pre>
  
  <p>Not much I am doing code wise. </p>
  
  <pre><code>       XDocument doc = XDocument.Load(xmlFileName);
  </code></pre>
  
  <p>I don't alter the encoding or anything. Any tips ?. </p>
