Message - which charset?

Message - which charset?

[Dmitry Yaitskov]

Hi,

Could somebody help me please? I want to set up my messages so that:

1) the charset of a message, if it is a reply or a followup, would be
the same as the charset of the original message (somehow I supposed
that this would be the default behavior but I don't think it is on my
system).

2) do something in the message buffer depending on the charset of the
message. I wanted to use the message-setup-hook for this but don't
know how to make sure that I have the charset available in the message
headers when the message setup hook is called. Even if I reply to a
message with a specified charset, I don't see it in the reply's
headers although I have message-generate-headers-first set to t.

Any advice would be much appreciated. Thanks.

If you are using a Mule-enabled Emacs, then that should be the case.

Well, there may be several charsets in an article, so there's no easy
way to do that.

(mm-find-mime-charset-region (point-min) (point-max))

will return a list of charsets in the current buffer.

Thanks, but no, I am using a non-Mule emacs. I don't want to pay the
performance penalty for the very limited multilingual support that I
really need. Basically, besides English I only *sometimes* need
Russian support in news and email - which would work fine out of the
box if it were not for the 2 different coding sysems used for Russian.
Even with that, most problems are solved by a lisp module enabling to
select the coding system. And with some simple elisp, I can now
determine which of the 2 coding systems is used in a particular
incoming message. My only problem left is - I'd like to be able to
specify the charset "of my choice" for the message that I compose (for
the whole message or for the 1st part of a mime one), based on the
headers/body of the (1st part of the 1st) message being replied
to/followed up. (For new messages, the default Gnus charset works
fine.) Is it possible to set up a hook like that to tell Gnus which
charset to specify?

Thanks, I will try to use it. I am not sure though this would help as
I'd like the list of charsets in the message(s) being replied to, not
the current (new?) one. In other words: while in the original message
buffer, I can determine (using mm-find-mime-charset-region or
otherwise) what the charset in the reply should be. Now, I hit
reply/followup/whatever, and in the new message buffer need to tell
Gnus somehow to change its "default" charset for this message only to
the one that I just found out in step 1. Is there a way to achieve
this? Thanks.

Try setting `message-default-charset', or making your simple elisp set 
it for you.

Thanks. Prob is - my "simple elisp" does a good job of determining the
charset of the message being viewed by gnus (run by
gnus-part-display-hook) - but when should I set the
message-default-charset? It is global (right?) and I don't want to
change it while I'm browsing my mail - I want to change it only when I
reply/follow up a particular message, and only for the duration of
that reply... Otherwise my message-default-charset would depend on
which particular message I last viewed, even if I happen to compose a
completely new message... any ideas? Or am I missing something here?
Thanks.

Well, you could hook into one of the message hooks,
e.g. `message-send-hook' and have "simple elisp" analyze the contents
of the message buffer.
