Hi,
I use GnuPG together with mutt on Debian Etch. I prefer to use
ISO-8859-1 and have these lines in my .muttrc to accomplish that:
set charset="iso-8859-1"
set config_charset="iso-8859-1"
set send_charset="iso-8859-1"
When sending a mail without using GnuPG (by selecting "clear" in mutt's
PGP menu), the above configuration results in the following content type
in the mail's header:
Content-Type: text/plain; charset=iso-8859-1
However, when signing the mail using GnuPG, the content type changes:
Content-Type: text/plain; charset=utf-8; x-action=pgp-signed
The body of the mail is also converted to UTF-8. My Danish characters
(æøåÆØÅ) end up being displayed incorrect at the receiver, as mutt still
inserts the following line in the header:
Content-Transfer-Encoding: 8bit
I have tried a lot of things to avoid the conversion to UTF-8,
unfortunately without luck:
- Using the mutt and GnuPG packages that come with Debian Etch (mutt
1.5.13 and GnuPG 1.4.6).
- Compiling my own versions of mutt and GnuPG (./configure without any
options other than --prefix, mutt 1.5.17, GnuPG 1.4.8).
- Invoking gpg with "--charset iso-8859-1".
- Invoking gpg with "--display-charset iso-8859-1".
- Having "charset iso-8859-1" in ~/.gnupg/gpg.conf.
- Exporting LC_ALL=en_DK before starting mutt.
- Exporting LC_ALL=en_DK.iso88591 before starting mutt.
- Invoking gpg with "LC_ALL=en_DK gpg ...".
- Invoking gpg with "LC_ALL=en_DK.iso88591 gpg ...".
- Searched Google (mostly without luck).
- Searched the gnupg-users@gnupg.org archive (on marc.info, completely
without luck).
I have run out of ideas. What else can I try? Can you spot something
wrong in what I have tried so far?
Please CC me when replying, as I'm not subscribed to the list. I have
attached my locale configuration and most of my .muttrc (the GnuPG
relevant part) inline. Thanks in advance.
Martin
