bug in pop3.el?

[Vladimir Volovich]

The following message is a courtesy copy of an article
that has been posted to gnu.emacs.gnus as well.

Hi!

i use pop3 to fetch mail from our POP3 server. when i happen to
receive mail with content-transfer-encoding=8bit, and there are
certain combinations of bytes in the message being received, i get an
annoying warning:

"The target text contains the following non ASCII character(s):" and
i'm asked to select a coding system to use to encode them. This often
happens e.g. for messages in utf-8 encoding.

Evidently, something is going wrong here, as pop3.el MUST NOT bother
with encoding of characters in message bodies: it should just put
everything AS IS, byte by byte; it is gnus' previewer which should
bother with encoding of raw 8-bit bytes in message bodies to certain
coding systems according to message headers!

i've set debug-on-entry for select-safe-coding-system and here is a
backtrace:

Sorry, but sending this to me is not going to get you anywhere, because I
do not support the code anymore.  Bug reports should go to the FSF.

OK, i've forwarded my message to news:gnu.emacs.bugs too (but still
got no replies).

BTW, pop3.el seems to be part of gnus --- at least it is distributed
with gnus. So maybe gnus maintainers (i.e. not as wide as FSF) are
responsible for bugs in pop3.el? In this case, could somebody look at
this problem?

And putting an info about maintainers of pop3.el would be a nice
thing, too.

I did not check in a long while, yet I think GNU mailing lists are gatewayed
into GNU newsgroups, but not the other way around, and the maintainers
usually check the mailing lists only.  The proper address to report an Emacs
bug, through the official channel, is probably mailto:bug-gnu-emacs@gnu.org.

Really?  This would mean that I should subscribe to help-gnu-emacs in
order not to miss anything?  Hm.

No, it means exactly the contrary.  You should subscribe to the newsgroup
if you do not want to miss anything, given of course, that you read the
articles from the newsgroup more often than your news provider expires them.
The reason why maintainers stick (or sticked) to the mailing list is that
they do not alway read newsgroups fast enough, while email just accumulate.

P.S. - But once again, these are old stories.  I did not check recently.
For a long while now, I've been using my own lists and avoiding FSF systems.
