iso-8859-1 in outgoing messages in spite of UTF-8 environment

iso-8859-1 in outgoing messages in spite of UTF-8 environment

[Stein Arild Strømme]

I have 

  (set-language-environment 'UTF-8)

How can I still get message-mode to use iso-8859-1 in outgoing
messages?  (I get complaints about UTF-8 email.)  Looking at the info
nodes for Message is quite confusing on this, and the things I have
tried do no seem to work, things like

  (setq mm-content-transfer-encoding-defaults '(iso-8859-1))
  (setq mm-body-charset-encoding-alist '(iso-8859-1 . 8bit))
  (setq message-posting-charset 'iso-8859-1)

I have these variables:

  message-default-charset is a variable defined in `message.el'.
  Its value is iso-8859-1

  message-posting-charset is a variable defined in `message.el'.
  Its value is iso-8859-1

Grateful for any hints.

emacs lisp is case sensitive (like Common Lisp, but unlike Common
Lisp, the emacs lisp reader doesn't upcase everything on read by
default).  Therefore 

   (set-language-environment 'UTF-8)

is not the same as

   (set-language-environment 'utf-8)

and I don't know whether 

   (set-language-environment 'UTF-8)

will do anything good at all.

In addition, you might add hooks to set the buffer encoding.

(defun mail-meat () (set-buffer-file-coding-system 'iso-8859-1))
(add-hook 'mail-setup-hook 'mail-meat)

I'm not claiming anything about the goodness of it, but it does work :-)

OK, I tried this (with message-setup-hook instead), and this does
indeed set the message composing buffer to iso-8859-1 (as read off
from the mode line).  However, when I send the message using C-c C-c,
it still turns into utf-8.

See the variable mm-coding-system-priorities.  For example, (setq
mm-coding-system-priorities '(latin-1 utf-8)) will ensure that Latin-1
is chosen over UTF-8 if possible.  You may wish to list more encodings
in that list, though.

Thank you very much, that seems to be exactly right.
