Oort Gnus v0.16
GNU Emacs 21.3.50.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2003-03-05 on tux
200 gnu.franken.de InterNetNews server INN 2.3.2 ready

I wrote to attached message using the TeX iput method (C-x RET c TeX RET).
Especially I added these quotes: \ldq \rdq and then \ldots and \euro .

Sending the message, Gnus choose this encoding:

MIME-Version: 1.0
Content-Type: text/plain; charset=macintosh
Content-Transfer-Encoding: quoted-printable

I would have expected UTF-8 since UTF-8 is more standard than
"macintosh"; I know you can set your preferences somehow -- but I'd
like to see Gnus doing the right thing out of the box.
