hexl-mode, while saving encoding problem

[Gelika PAPP-RAFFY]



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,
