Thank you for your answer. I finally understand what you mean. I have
struggled the whole day with that restriction, but now when I again
read your text, I understand. You answer solves all my problems.
I never understood the footnote in the book either. It says
something about "composites", but nowhere could I found how to make
those composites. That was exactly what I wanted to do. Now I finally
know how to do it. 

I have some more related questions:
What is the "ISOLatin1Encoding" (or something like that) symbol doing
in the system dictionary?

On the hard-disk of the Agfa 3400 PS laser-printer there are some
files. One called "AdobeStd.ps", another "ISOAdobeStd.ps". Both seems
to define an encoding where "A" is 1, "B" 2, and so on. That is, all
characters in name-alphabetic order. What are those files doing there?
