I confirmed the following form works for only the first time.
But it returns "" thereafter.

(require 'mel)
(mel-use-module 'mel-q-ccl '("quoted-printable" "Q"))

(with-temp-buffer
  (set-buffer-multibyte nil)
  (insert (encode-coding-string "Grüß Gott\n" 'utf-8))
  (funcall (mel-find-function 'mime-encode-region "quoted-printable")
	   (point-min) (point-max))
  (buffer-string))

Ito-san, is it due to Emacs bug?
