Public bug reported: Hi,
please see following bug report on freedesktop with screenshots: https://bugs.freedesktop.org/show_bug.cgi?id=79527 When fonts package "fonts-texgyre" from the "texgyre" package is installed, all PDFs containing e.g. a reference to a "Helvetica" font, which is usually not installed on Ubuntu systems, fontconfig mages a very bad choice with one of the fonts supplied in fonts-texgyre (like "TeX Gyre Heros"). The problem is, apparantly the texgyre fonts us a different naming style for some important glyphs (like greek characters contained in many mathematical documents), so that fontconfig cannot find them. See screenshots in abovementioned bugreport: ==> PDF readers only display a blank space in this case, which has potentially disastrous results (there are six orders of magnitude difference between an Ampere current and a Microampere current e.g..). There is a likely explanation also unter this bugreport: https://bugs.launchpad.net/ubuntu/+source/tex-gyre/+bug/1317599 ==> Please change the Ubuntu font configuration so that all those PDFs are displayed correctly. ** Affects: fontconfig (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1326188 Title: Wrong PDF standard fonts are replaced when fonts package "fonts- texgyre" is installed - PDFs are rendered with missing characters To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fontconfig/+bug/1326188/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
