That page is a somewhat different case. There's more than the copyright 
sign that is wrong there, namely the registered sign and two occurrences 
of e with acute (in the name "José"), too. Moreover, the page says
   <?xml version="1.0" encoding="iso-8859-1"?>
_and_
   <meta http-equiv="content-type"
   content="application/xhtml+xml; charset=UTF-8" />
but what really matters is the HTTP header
   Content-Type: text/html; charset=iso-8859-1

If you manually change the encoding used by a browser to UTF-8, the é's 
become right and the two other non-ASCII characters become a little less
obscured by extra characters before them. There _is_ a "double UTF-8" 
involved, too, but the primary problem is that the declared encoding
is not the one actually used on the page.
