Forwarding a mail, with a non-ASCII signature

Forwarding a mail, with a non-ASCII signature

[Lele Gaifax]

Hi all,

as you can see below, my signature contains some non-ASCII characters,
and it is stored as UTF-8 (I have `(prefer-coding-system 'utf-8)` in my
.emacs.el) in my home as ~/.signature.

Recently I started using notmuch with Emacs as the main MUA, using
message-mode to send emails. I'm *very* satisfied, BTW!

Everything works great, except that when I "forward" an email message:
in that case, the "*unsent mail*" buffer contains the original message
within a "#mml" tag, followed by my signature, apparently appended as
binary (e.g. instead of "vivrò" I see "vivr\303\262"). When I try to
send it, I get the "Unreadable characters" prompt...

I quickly inspected what notmuch-show-forward-message does, but AFAICT
it does very little, delegating most of the work to message-mode: but
doing the same from Gnus works ok, so I must be missing something.

I also tried tweaking the message-default-charset, changing it from nil
to utf-8, with the very same result.

I'm using Emacs 24.4.51 compiled a few days ago, if that matters.

Thank you for any hint,
ciao, lele.

It doesn't seem to matter here, but are you really not using
notmuch-mua-new-mail to send emails? Your User-Agent field seems to
concur:

User-Agent: Gnus/5.13 (Gnus v5.13) Emacs/24.4.51 (gnu/linux)

I can reproduce this.


BR,

Yes, I prefer interacting with most ML thru gmane.org, so this message
originated from Gnus.

How do you insert the signature? That is, do you have some bits of
configuration that add the signature to outgoing messages?

Nothing special, just the following config snippet in my .gnus.el::

    (setq gnus-posting-styles
          '((".*"
             (signature-file "~/.signature")
             (name "Lele Gaifax")
             (organization "Nautilus Entertainments"))))

Yes! This works great, with it the forward buffer contains the signature
loaded with the correct encoding, and the sendmail succeeds without
prompting about unreadable chars.

Thanks a lot for fixing it,
ciao, lele.

That's good, thanks for testing. I'll work up and submit a proper patch.

Thanks a lot, waiting to see it landing on the MELPA archive.

Just be aware that people have had problems in the past using versions
from MELPA because they ship only the elisp and not the corresponding C
code.  Hopefully it works better now, or at least detects dangerous
version mismatches between the elisp and C code.
