    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 "Josť"), 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 ť'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.
