I use gnupg-1.4.1 on GNU/Linux (up-to-date Gentoo, Linux 2.6.12 on AMD64 if it matters) to sign and encrypt my mail, and everything is fine as long as I stay with strictly us-ascii. However, when I use other characters (mostly national characters covered by iso-8859-15), gnupg converts the input data to UTF-8 when signing, wreaking havoc with those characters. The fact that gnupg converts back when verifying or decrypting the data only makes matters worse since *I* am unaware of the problem that others face in reading my e-mails.
My gnupg.conf explicitly states "charset iso-8859-15" so that cannot really be the problem. (It's the only charset-related setting in effect for gnupg, I have checked and triple-checked this.) My MUA, muttng, correctly identifies the input data prior to signing as iso-8859-15 and after signing as utf-8, but a lot of mailers don't seem to deal very well with UTF-8 data. Not clearsigning the message avoids this problem, but is hardly an ideal solution. PGP/MIME signing is not really an option either, considering the number of broken MUAs out there. This appears to only be a problem with clearsigned messages, not PGP/MIME messages (for some odd reason) which leads to my question: How do I get gnupg to ignore the charset of the input data and just leave it *as is* when clearsigning? The exact command lines used are (long): Clearsigning: /usr/bin/gpg --no-verbose --batch --quiet --output - --passphrase-fd 0 --armor --textmode --clearsign -u $SIGNING_KEY_ID $FILENAME PGP/MIME signing: /usr/bin/gpg --no-verbose --batch --quiet --output - --passphrase-fd 0 --armor --detach-sign --textmode -u $SIGNING_KEY_ID $FILENAME No radical differences there, the only one I can see is --clearsign and --detach-sign and the ordering of --textmode and the signing option. I looked through the archives for almost a year back and couldn't find anything of relevance, but if I missed something, please feel free to let me know. -- Michael Kjörling, [EMAIL PROTECTED] - http://michael.kjorling.com/ * ASCII Ribbon Campaign: Against HTML Mail, Proprietary Attachments * * .....
