Gnus 5.6.45 does this automatically with mime-support enabled
(tm-edit 7.108), however pgnus hat its own native mime support
and rfc2047 header encoding is not enabled by default.

I created the original header *manually* ;-)

Not for my setup (plain Debian xemacs 20.4 and pgnus <= 0.87 - without
any additional setttings in my .emacs and .gnus configuration

(pgnus up to 0.88, xemacs 20.4 Debian 2.1 / emacs 19.3 Suse 6.1)

How can I activate this feature?

I browsed the ding mailing lists and couldn't find an answer.


Thanks a lot for your help.

That's a real problem. Accoring to offical Usenet RFCs, usenet headers
have to be 8bit clean - 8bit chars may only occur in rfc2047 (qp)
format.

I've been flamed multiple times for 8 bit headers not being rfc
2047-encoded in my pgnus usenet headers. According to my
investigations, the flamers were right.

Thus, Gnus should use RFC2047 header encoding for news, too.

Unencoded 8-bit headers are prefered in the dk.* hierarchy, because
that is supported by most news agents in use.  I suspect the situation
is the same in the no.* hierarchy.

Correct. I believe the same goes for relcom and a few other
hierarchies. The header charset must of course also be specified.

I must say that I am surprised to hear about flaming based on 8bit
chars in Usenet headers. I've posted hundreds of articles in comp,
rec, alt, news and a few other hierarchies, and never been flamed
(well, at least not for the header encoding :-). All of the articles
have had at least one header with 8bit chars (because of my name...)
and a working mail address.

The reason is of course that 8bit headers don't cause any problems for
anybody. The chars may not always look like they were supposed to,
but that's not important (I don't care whether people call me Bjørn,
Bjxrn, Bj|rn, Bjorn, or Bj¤rn). What's important is that rfc2047
really fucks up readers that don't understand it, and makes the text
unreadable. I do not like being called =?iso-8859-1?q?Bj=F8rn?=. You
will really need your flameproof suit if you post something like that
in no.*

Therefore 8bit for news and rfc2047 for mail (where you have more
control over the client software in the other end) is a reasonable
default. But it should be possible to change it based on hierarchy,
and IIRC it is. I just don't remember how. Anybody?

It's controlled by `gnus-group-posting-charset-alist', but I don't
really like that variable.
