Is it really practicable for people who read German?  I'm worried
those contents don't seem to be decoded correctly (I don't care
what they say since I don't read German, though).  For example,
the quotation marks `“' and `”' and the hyphen `–' seem to have
been encoded as \223, \224 and \226 respectively in the server.
I guess the fau.org server use the `windows-1252' coding system
even if it is not specified in the header information.  To solve
the problem, ARISAWA Akihiro proposed the following:

(defvar shimbun-fau-coding-system
  (or (shimbun-find-coding-system 'windows-1252)
      (shimbun-find-coding-system 'latin-iso8859-1)))

;; It should be put into shimbun.el.
(defalias 'shimbun-find-coding-system 'w3m-find-coding-system)

The value of `shimbun-fau-coding-system' is passed to
`detect-coding-with-priority' as the topmost of the priority
list by way of `w3m-decode-buffer'.  However, Emacs doesn't
always decode the contents correctly because Latin-1 is superior
to `windows-1252' there.  I think the best solution is to fetch
the raw contents and to decode them by itself.  The patch is
below.  Although it cannot help Emacsen in which `windows-1252'
is not supported, it is better than do nothing.  WDYT?
