<p><pre><code>  /somecategory/apage.php?id=34\xc3\x83\xc6\x92\xc3\x86\xe2\x80\x99\xc3\x83\xe2\x80\x9a\xc3\x82\xc2\x9d&#38;listing=989

Thing is, removing that hex and just putting in<p><pre><code>  /somecategory/apage.php?id=34&#38;listing=989 
</code></pre>
does the same thing. I get the same output to the browser regardless of which is used.
