Heiko, you are, I believe, a native German speaker
(please correct me if I am mistaken).  In your
personal opinion, are the following "letters",
"arbitrary rubbisch", or "funny stuff" ?

	ä, ö, ü, ß, ł, ę

(FWIW, they are all clearly letters IMHO, with
the possible exception of ß which might, I suppose,
be a ligature-digraph).
