Gnus & Quoted-Printable

Gnus & Quoted-Printable

[Samuel Tardieu]

Every few years, when I configure my Gnus, I face the same problem:
how can I make sure that Gnus will *never* *ever* send
quoted-printable when posting news and even mail?

Customize mm-body-charset-encoding-alist. E.g.:
,----
| (add-to-list 'mm-body-charset-encoding-alist '(iso-8859-1 . 8bit))
| 
| (if (mm-coding-system-p 'iso-8859-15)
|     (add-to-list 'mm-body-charset-encoding-alist '(iso-8859-15 . 8bit)))
`----

Best regards,

Content-Type != Content-Transfer-Encoding

Huh? Can't say that I understood that. AFAICT both
mm-body-charset-encoding-alist and mm-coding-system-priorities both
are for encoding, at least after reading the output from C-h v.

Either the documentation of those variables are incomplete or I have
misunderstood something fundamental.

Could you please explain?

It contains:

((iso-latin-1 . 8bit)
 (iso-latin-15 . 8bit)
 (iso-8859-1 . 8bit)
 (iso-8859-15 . 8bit)
 (utf-8 . 8bit)
 (iso-2022-jp . 7bit)
 (iso-2022-jp-2 . 7bit)
 (utf-16 . 8bit)
 (utf-16be . base64)
 (utf-16le . base64))

A test message I just sent in fr.test contains:

| Content-Type: text/plain; charset=ISO-8859-15
| Content-Transfer-Encoding: quoted-printable

I am puzzled...

The last should be iso-latin-9 not 15 (iso-8859-15 = latin-9), but I am
not sure that the problem is here.

That work's only with the standard gnus from

Customise `gnus-group-posting-charset-alist' -- in particular the
(message-this-is-mail ...) entry.

But note that doing this for email violates RFC 2822 (it's also
rumoured to be unhealthy for pigeons, or something).

I did it, to no avail...

I even changed the message-this-is-mail setting just to check (I am
using news and was OK to hurt avian carriers). The current value is:

(("^\\(no\\|fr\\)\\.[^,]*\\(,[ 	\n]*\\(no\\|fr\\)\\.[^,]*\\)*$" iso-8859-1
  (t))
 ("^\\(fido7\\|relcom\\)\\.[^,]*\\(,[ 	\n]*\\(fido7\\|relcom\\)\\.[^,]*\\)*$" koi8-r
  (koi8-r))
 (message-this-is-mail nil t)
 (message-this-is-news nil t))

I ended up with yet another test message in quoted-printable...

It works for me.  Ah, you're not using a vanilla Gnus:

User-Agent: T-gnus/6.16.2 (based on Gnus v5.10.2) (revision 02) SEMI/1.14.5 (Awara-Onsen) FLIM/1.14.5 (Demachiyanagi) APEL/10.6 Emacs/21.3 (i386--freebsd) MULE/5.0 (SAKAKI)

All bets are off for this, as it uses a completely different MIME
library than Gnus -- don't expect anything charset related in the Gnus
manual to be true for this version.

You probably have to read the manual for SEMI, FLIM or APEL to figure
it out.

Thanks Jesper, that was it. I had no particular reason to use T-Gnus,
so I switched to the vanilla Gnus included in Emacs. This works much
much better :)
