Encoding Decoding problems in TreeBuilder

I'm running web pages through HTML::TreeBuilder and certain chracters,  
namely < , >, ', and & are being encoded. For example, I ran the  
following text through TreeBuilder:

      The dog's collar 4 > 2 and 2 < 4 & amper

And the output is:

      The dog&#39;s collar 4 &gt; and 2 &lt; 4 &amp; amper

My question then, is this the expected and acceptable behavior for  
TreeBuilder? According to W3.org,  
http://www.w3.org/TR/html4/charset.html, a user agent (browser) will  
translate character sets, but TreeBuilder isn't purporting to be a  
user agent as LWP would be or is it????

I'm confused and need clarificaiton.

I am using TreeBuilder 3.13 and I have HTML::Tree 3.20 installed on  
Perl 5.8.7.
