Because w3m-current-content-charset is nil, w3m-fix-fscked-latin-1
does nothing (I checked it only with sb-zeit-de).  We need a way
to know the contents use Latin-1 and the extra data there.

I think ones who extend the Latin-1 specification is not us even
if Mozilla temporizes to the standard which someone has invented
arbitrarily.  We cannot help to do that if it is the only way,
though.

Yes.  But there's a way to support windows-1252 even in Emacs 21.

To use this is different than enhancing the Latin-1
specification arbitrarily.  Even if XEmacs and old Emacsen don't
work with it, it cannot be helped.  It is similar that there's
no way to display images in Emacs 20.

It can become a reason why we enhance the Latin-1 specification
in emacs-w3m.  However, I'm not yet convinced which is better,
enhancing Latin-1 or providing windows-1252.
