"I also had this problem, a pdf-file (probably generated in Windows- Word) shows wrong symbols for \mu, \Omega etc. To solve this I removed a package named ttf-symbol-replacement and it now works as expected. I also has a package called ttf-symbol-replacement1.3 (probably from the wine ppa) and if I install that it also works." It's likely that all of you that are having this problem have wine installed, I think wine pulls in that package. After I removed the font, scientific symbols displays correctly in Evince. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to poppler in Ubuntu. https://bugs.launchpad.net/bugs/518236 Title: Evince/Okular displays incorrect characters -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
