Dear Reinhard,

can be used for base 14 fonts. This is a limitation of PDF, not pdftex.
In a pdf document you cannot change the FontMatrix as you can do in PostScript. Therefore pdftex has to manipulate the font itself when it is inserted. If you run pdffonts (from xpdf) on your pdf file you'll see that the same font is embedded for each expansion step.
It is certainly mentioned in the pdftex manual. If not, complain.
Thanks a lot. It will be better for pdf[ex]TeX to exit with an error message without causing access violation, when a user calls hz without embedding relevant fonts. Best regards Akira
