Hallo Wolfgang,

...

But what is wrong with my code? Why does it not work?

Take a look at the log file when the font is read.

load afm | reading /Users/wolf/context/tex/texmf/fonts/afm/public/wasy/ wasy10.afm load afm | unifying /Users/wolf/context/tex/texmf/fonts/afm/public/ wasy/wasy10.afm afm glyph | assigning private slot U+F0000 for unknown glyph name AC afm glyph | assigning private slot U+F0001 for unknown glyph name kreuz ... afm glyph | assigning private slot U+F0016 for unknown glyph name saturn ...

I can not find such lines in the log file. Do you have some special switches? Wolfgang
