FWIW: 1) it also displays ok in atril 2) The 'scattered mathematical symbols' appear to me to be in the right places - ie it's just that they're the only bit that displays correctly. Perhaps some kind of missing font issue? 3) the stderr out from (at least) okular and xpdf look like they might be useful to someone who understands the topic better, but do look like something is missing.
