[VM] displaying text/html with utf-8 via w3m

[Ralf Fassel]

emaccs 23.2.1, VM 8.2.0b

Could some kind give me a hint where to look:

I get mails with headers
  Content-Type: text/html; charset=UTF-8
  Content-Transfer-Encoding: quoted-printable
  
with the body e.g.

    <br>
    Bin auf Gesch=C3=A4ftsreise.
    <br>

(The =C3=A4 in there is lowercase umlaut-a).

After Decoding via w3m this looks like this in the INBOX Presentation
buffer

    Bin auf Gesch ftsreise.

The umlaut-a has been replaced by a space.  If I run the text manually
through w3m, the ouput still contains the utf-8 character, just the
HTML-markup is gone.  But after inserting in the Presentation buffer the
umlaut is changed to a space.

This also happens on emacs -q -no-site-file, so I guess it is something
more basic than my customizations.

Any clues?
