I changed my mind, while working on the customization stuff. I started
to implement it according to your previous suggestions. But I realized
that specifying a cons cell as FONTNAME argument to `set-fontset-font'
does not seem to work with non-ASCII charsets either. I tested it with
an Emacs without my modifications:


(set-face-font 'default "fontset-test")

(set-fontset-font "fontset-test" 'latin-iso8859-1 '("misc-fixed" . "iso8859-1"))

Now when I type some umlauts like "äöü" Emacs still displays them in

But it works, when I specify a fontname:

(set-fontset-font "fontset-test" 'latin-iso8859-1

Am I missing something?

It would, of course, be easy to change `set-fontset-font' to generate
a fontname string from such a cons cell, so that:
("misc-fixed" . "iso8859-1") ==> "-misc-fixed-*-iso8859-1". But as
far as I understand the code, this is not the way it is supposed to
work for non-ASCII fonts, therefore I ask.
