[Message part 1 (text/plain, inline)]

Hello. I have now tested this with versions 24.3, 25.3 and latest 28.2. All
have this problem.

First I create a new file with c-x c-f. By default, it has coding system
iso-latin-9-dos.

I change the coding system to utf-8 via the buffer's bottombar. Char "0"
changes to "U".

Then I write "äöäöäö" and quit emacs.

When I rerun the emacs and open the text, the "öä" looks wrong and coding
system is back at iso-latin-9-dos.

I use Total Commander's View to verify the file is ok. The file goes wrong
only if I now save the buffer.

What helps is c-x ret r which asks the coding system -- I type utf-8.

Also helps when I add ";;; -*- coding: utf-8-dos; -*-" to the top of file.
I will use this method as solution, but this is too advanced for regular
users -- please check what is the problem.
