Well, dvi files only contains the name of the tex font. What textpath does is to pick up corresponding type I font and convert them to path using the freetype library (as far as I know, this is what dvipng and matplotlib pdf backend does). So, my guess is that, textpath is somehow picking up wrong fonts, or wrong glyphs. The code works fine at least in my mac os X tiger w/ texlive 2008, and in ubuntu with texlive 2007. As I don't have any access to mac os X 10.6, it would be hard to track down what is wrong. Here are a few more test I wish you to run. *) Check if pdf backend produces a correct result. Do not use textpath example, but simply use text command with usetex=True, and see if the pdf output is okay. FWIW, the textpath code is largely borrowed from the pdfbackend. *) Run the attached code, and post the terminal output. The output is basically the name of the tex font and the name of the substituted type1 font, etc. For your reference, here is my output. texname, type1name, enc, char_id cmex10 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmex10.pfb None CMEX10-34 cmsy10 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmsy10.pfb None CMSY10-49 cmex10 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmsy10.pfb None CMEX10-88 cmmi12 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmmi12.pfb None CMMI12-110 cmr17 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMR17-61 cmr17 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMR17-49 cmsy10 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMSY10-0 cmmi12 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMMI12-101 cmmi12 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMMI12-105 cmmi12 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMMI12-25 cmr17 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMR17-50 cmmi12 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMMI12-110 cmex10 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMEX10-35 pncr8r /usr/local/texlive/2008/texmf-dist/fonts/type1/urw/ncntrsbk/uncr8a.pfb /usr/local/texlive/2008/texmf-dist/fonts/enc/dvips/base/8r.enc Century%20Schoolbook%20L%20Roman-232 Regards, -JJ
