title: How to add html entites to RSS feeds
body: <p>I use htmlentities on data that are displaying in RSS and I have unicode characters so they are show entities like <code>&amp;Aacute;</code> which service like <a href="http://feedvalidator.org/" rel="nofollow">http://feedvalidator.org/</a> show as invalid.</p>
  
  <p>How can I add this entities to xml (like using namespace) or should I use different function to escape characters like <code>&amp; &lt; &gt;</code>?</p>
