title: NSXMLParser rss issue NSXMLParserInvalidCharacterError
body: <p>NSXMLParserInvalidCharacterError # 9 </p>
  
  <p>This is the error I get when I hit a weird character (like quotes copied and pasted from word to the web form, that end up in the feed).  The feed I am using is not giving an encoding, and their is no hope for me to get them to change that.  This is all I get in the header:</p>
  
  <p>&lt; ?xml version="1.0"?>
  &lt; rss version="2.0"></p>
  
  <p>What can I do about illegal characters when parsing feeds?  Do I sweep the data prior to the parse?  Is there something I am missing in the API?  Has anyone dealt with this issue?</p>
