Hello,
 
I am editing binary files with emacs (ID3 tags in .mp3 files).
I use the hexl-mode.
When I want to save my modifications I get the question "Selet coding system" and it is asking me to choose between several like undecided-unix, mule-utf-8, etc.
 
But I don't want to encode the text, it is pure binary!
I tried to do with the "undecided" but it still modifies (and corrupts) my file.
 
Is there any possibility to overcome this problem?
 
Thanks for any help,
 
Gelika
