If you intend to send UTF-8, you MUA should not declare it as
"Content-Type: TEXT/PLAIN; charset=ISO-8859-1".  ;-)

AFAIK, you can write the chars in UTF-8 if you specify the encoding of
the lisp file, cf. (info "(emacs)Specify Coding"):

--8<---------------cut here---------------start------------->8---
;; -*- coding: utf-8 -*-
(defun rs-test ()
  (interactive)
  (re-search-forward "[ÄÖÜäößü]"))
--8<---------------cut here---------------end--------------->8---

I don't know if there's a reason why isn't used in `ispell.el'.

Bye, Reiner.
