Ok... I'm running python 2.5 on winxp. I recently upgraded from matplotlib 88ish to 91.1, and now the font embedding in eps files no longer works for me: all fonts end up as paths when I open an eps file in illustrator, and I can't do any font editing like I could before I upgraded. I found a reference to changing ps.fonttype to 42 on one of the matplotlib faq pages to embed the entire truetype font in the eps file, but when I do that illustrator can't open the eps file, failing with "The operation cannot complete because of an unknown error." How do I make the fonts editable in illustrator again?
