There are five symbols you need to handle.

&<'>" and they should be encoded as &amp; &lt; &apos; &gt; and &quot;

Those are the five default entities that must be encoded.  Other 
symbols can be encoded using unicode numbers.  Just make sure you 
don't double-encode unless it's actually needed.

The only time you'd need to double encode would be if you actually 
intended to show one of the symbols.

<description>This is &lt;b&gt;bold&lt;/&gt; text</description>

Would give a sentence with the word bold in HTML bold.

If, however, you wanted to talk about the encoding itself you'd need 
to double encode:

<description>To show bold text you'd use 
&amp;lt;b&amp;gt;bold&amp;lt;/&amp;gt;.</description>

This gives you the sentence "To show bold text you'd use <b>bold</b>."

Tricky but not all that hard once you get the idea.
