If you want to avoid both (confirming each time as well as frobbing
enable-local-eval) you could set some variable of your own in the
local variables section (everything below is untested)  …

-*- my-input-method: lirum-larum -*-

… and then put something like this into your .emacs:

(defvar my-input-method nil
  "Preferred input method local to a file.
This variable is meant to be set in the local variables section.")
(make-variable-buffer-local 'my-input-method)

;; When visiting a file, check whether `my-input-method' is non-nil
;; and set the current input method accordingly.
(add-hook 'find-file-hooks
          (lambda ()
            (when my-input-method
              ;; I seem to recall that the argument to
              ;; `set-input-method' is supposed to be a string, but I
              ;; can't check right now.
              (set-input-method (symbol-name my-input-method)))))

I think this method would also be useful for setting up file-specific
indentation styles, btw.
