Hi all, I stumbled over an issue with the subject these days, which I aleady saw 1-2 years ago, causing the subject to be displayed corruptly on another device.
It looks that there are inconsistencies in various places (even on the other device), and - while preparing for a fix - more knowledge about how it should be is highly welcome. I created it in Gitlab as https://gitlab.com/muttmua/mutt/-/issues/289 So if anyone knows how to sort things - please respond. I can also be available for a conversation on IRC or via phone (will send my number on demand). Summary: A subject "Große wordxxxx word wordxx" (edited in utf-8 locale, "ß" is 2 bytes) in composing messages ends in the message as (raw) Subject: =?iso-8859-1?Q?Gro=DF?= =?iso-8859-1?Q?e?= wordxxxx word wordxx Although this is technically valid, these are consequences * word "Große" is split into 2 encoded blocks * I interpret RFC2047 that separating encoded blocks by space (without newline) means two words, so space should be displayed to the user as-is (Mutt doesn't display the space, but this probably is a different story) * This causes interoperability problems: In iOS mail app the "ß" is displayed as invalid character (which also is insane behaviour, as encoding for the character is fine - well, the form of encoding by Mutt is also "special") Gero
