Yes, I know that the fonts are subsetted.  So one should re-merge them.  Even if keeping them separated if the encoding is different.

pdffonts tells me that Unicode is used, if I am not mistaken.

Well, I can always program a switch to either include the YiKZ source and comile it or include the graphic. Only for the final version.
