Save Special Characters without Question

Whenever I am using finnish special characters äöå, emacs starts asking "Select coding system (default iso-8859-1):", when I am saving the file.

It is something that I can quickly pass with enter, but I really would prefer to have something in my ~/.emacs file to handle those cases. Since only coding-system that I care about is iso-8859-1, I want to hammer it into my emacs and avoid all those stupid questions.

Suggestions:

Add either of the following lisp to your ~/.emacs file:

• Note: semi-obsolete:

        (standard-display-european t)
        

•       (set-language-environment 'Latin-1)
        (setq default-input-method "latin-1-postfix")
        (set-input-mode nil nil 'euro 7)
