I have a lot of filenames in Russian in my file system. Every time I close Emacs if I had eshell opened, it shows a *temp* buffer with a list of directories. And asks 2 questions:

  1. Select coding system (default utf-8):

    I click enter

  2. Selected encoding utf-8 disagrees with latin-2 specified by file contents. Really save (else edit coding cookies and try again)? (y or n)

    I click "y", enter

What file cookies is he talking about? Where can I set it to utf-8, so this question is never asked again?

Update

I found the wrong file: ~/.emacs.d/eshell/lastdir. I saved this: "яОяН­яОяННяОуВяНЕяОяОяННяОяНОяОяНВяОяНА" instead of normal Russian name. Then it tries to save it again.

  • I can't find any mention of such a file "cookie" in the manual, may it may refer to gnu.org/software/emacs/manual/html_node/emacs/… – JeanPierre Apr 3 '17 at 19:06
  • @JeanPierre Maybe, it tries to save the history of eshell somewhere? – user4035 Apr 3 '17 at 19:09
  • Do you have all of the following set? (setq locale-coding-system 'utf-8) (set-terminal-coding-system 'utf-8) (set-keyboard-coding-system 'utf-8) (set-selection-coding-system 'utf-8) (prefer-coding-system 'utf-8) – mclear Apr 5 '17 at 3:23
  • @mclear Tried, didn't help. Please, see the update: I found the file that causes the error, but don't know, what to do with it. – user4035 Apr 5 '17 at 8:02

I was facing a similar problem i.e while closing the Emacs (my version 26.3), I was repeatedly prompted about the encoding: Select coding system (default utf-8):

I solved the problem by deleting some entries from .emacs.d/ac-comphist.dat file (in my case, the character is the lowercase lambda λ).

  • Sounds like a bug in the package that writes ac-comphist.dat. Please report it accordingly. – Stefan Apr 19 at 1:50
