When the subject ends with a character whose last byte in UTF-8 is either 85 or A0, it appears the character collapses. To reproduce:
- prepare .mutt/muttrc containing only the following line: set edit_headers=yes - launch mutt and type m to create a new mail. - enter some e-mail address and a subject. - vim launches. - edit Subject line so that it ends with a character such as: υ or % or e (whose last byte of their UTF-8 code is 85) or ム or 加 (whose last byte of their UTF-8 code is A0). - type :wq to quit vim. - the last character is converted to something else. Would it be possible to somehow avoid this problem? I cannot avoid creating e-mails with Japanese characters in Subject and this problem bugs me quite much. I am using Mutt 2.2.3 (2022-04-12) installed from homebrew on MacOS Big Sur 11.6.7 on iMac (2019). Sincerely, -- Kenichi Asai
