I've been noticing I get some messages where the subject begins with =?US-ASCII?Q?<the subject>?=. I looked this up on google (took some time because a ton of things come up when you just look for the string) and finally found RFC 1342, which said that this was non-ascii text, and that the character set is what appears after the =? (us-ascii in this case, instead of ascii).
After reading this, I decided to see what other IMAP clients saw when they displayed these messages, and they do not show the us-ascii thing, which means that they understand rfc 1342. Is there a way to get mutt to do so, also? Or does mutt use some external program I need in order to do this? Thanks! Jen
