Subject: editing .mp3 in binary mode
--text follows this line--
I am editing an .mp3 file (the ID3 tag of an mp3 file) in binary mode. (hexl-mode). When I want to save it, it asks me for some encoding option, whereas it should be left as it.
Adding the line
(add-to-list 'file-coding-system-alist '("\\.mp3\\'" . no-conversion))
in .emacs is sufficient to solve the issue.
Probably also other compressed audio files extensions should be added, like .wma, .aac, .m4a, .ogg etc.
