Problem with invalid characters when using notmuch-reply

[Albin Stjerna <albin.stjerna@gmail.com>]

Hi!

I have a very confusing problem. When replying to a message containing special characters (read: non-ascii), they show up as mysteriously escaped characters, such as \345 (where the letter ä should be). When sending these replies, I get an error about my message containing non-printable characters. When these messages arrive, the special characters (even those I entered, that looked fine in the mail compose buffer) are garbled.

Everything works fine when composing a new message. The problem only appears when replying. The problem appeared quite recently, apparently out of nowhere. No emacs upgrade, no notmuch upgrade (as far as I can recall).

The problem is appears in both Emacs 23 and 24, and restart (neither of Emacs nor of my computer) doesn't help.

Also:
albin@hecate ~ % notmuch --version
notmuch 0.13

albin@hecate ~ % locale
LANG=en_US.utf8
LANGUAGE=
LC_CTYPE="en_US.utf8"
LC_NUMERIC="en_US.utf8"
LC_TIME="en_US.utf8"
LC_COLLATE="en_US.utf8"
LC_MONETARY="en_US.utf8"
LC_MESSAGES="en_US.utf8"
LC_PAPER="en_US.utf8"
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT="en_US.utf8"
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=

notmuch reply (on the command line) seems to work just fine.

Any pointers you can give me would be greatly appreciated!

Thanks in advance,
  Albin
