It looks like my script did what it was meant to do up to this point.
Unfortunately I don't know much about the inner workings of ghostscript;
I just copied this command from an example given in the ghostscript
documentation.
I would be interested to know if these fonts are still listed as
embedded if you run pdffonts on the final -NOFONTS.pdf. I will ask
Dotan to send me his original file; maybe there is some document
security option which has to be overridden.
Please let us know if you think of anything else in the meantime; your
earlier suggestion about the ghostscript fonts was what made me realize
that the problem could maybe be solved by using ghostscript to remove
the offending fonts from the PDF.
