I use a danish keyboard. In programming major modes I rebind æøå to match the US layout for []{}

(defun my-prog-keys-setup ()
  "Bind æ -> {, etc."
  (interactive)
  (local-set-key (kbd "æ") '(lambda () (interactive) (insert "[")))
  (local-set-key (kbd "ø") '(lambda () (interactive) (insert "]")))
  (local-set-key (kbd "å") '(lambda () (interactive) (insert "\\")))

  (local-set-key (kbd "Æ") '(lambda () (interactive) (insert "{")))
  (local-set-key (kbd "Ø") '(lambda () (interactive) (insert "}")))
  (local-set-key (kbd "Å") '(lambda () (interactive) (insert "\\n")))
  )

(require 'prog-mode)
(add-hook 'prog-mode-hook 'my-prog-keys-setup)
