Changing charset for posting news

Changing charset for posting news

[David Sumbler]

Although it has not caused a problem until recently, my use of UTF-8
and "quoted printable" has caused problems in a newsgroup which I
recently started using.  Basically, I have been told in no uncertain
terms to avoid them.

However, I am unclear how to change this, although I have read section
3.19 of the Gnus Manual.

How do I ensure that, when posting news, my messages are sent in
ISO-8859-1, and avoid "quoted printable"?

replace "nospam" in my address with "aeolia".

I should perhaps have added that the problem arises when using French
characters, e.g. « à é ç ».  When I write using just standard English
characters, Gnus/Emacs sends it as "Content-Type: text/plain;
charset=us-ascii"

In the general case, you can’t do this without losing data. If you write
exclusively English, this should work, though it hasn’t been tested;

(setq mm-coding-system-priorities '(iso-8859-1))
(add-to-list 'mm-body-charset-encoding-alist 
             '(iso-8859-1 . 8bit))

Thanks - I've added that to my .gnus file, and it seems to work.  I
write in English and, sometimes, French, so this is fine.

You can test this on a private group - no need to send test messages
to the 'troubled' newsgroup (UTF-8 is here to stay :)

Hit `G c' on the group that you want to customize.  Set the preferred
charset to iso-8859-1.  Save.  That should do it.  The Gnus manual
should have more information on this - I don't use it myself, so the
manual is the authoritative source.

The advice you were given to use iso-8859-1 globally will work, but
it's not necessary when you can override the posting charset only for
a specific group.

Strange: I have tried this, having commented out in .gnus the lines
suggested by Aidan, and it doesn't work!  Despite having specified
iso-8859-1, as you suggest, messages I send to the fr.test group still
are sent as UTF-8 and quoted printable.

That’s a bug that some changes I made tickled, according to this mail:

http://list-archive.xemacs.org/xemacs-beta/200505/msg00121.html

But I’ve looked into this some more, and, well, the design of that code is
hugely broken--loads of programming using and endorsing underdocumented
dynamic binding, crazy return values--and I haven’t seen an example where
setting mm-coding-system-priorities appropriately is broken. I’ll put
together a patch removing support for newsgroup-specific character sets if
this sounds reasonable. 

If not, I’ll look into adding support for binding message-posting-charset
around calls to mm-find-charset-region, which should re-add support for the
charset-per-newsgroup approach.

That's strange.  I wonder if it's a bug or just a feature that was
never implemented.  Does anyone know?  If not, I'll look into it when
I get a chance.
