Erik, could you please do me a favour and test a package for me? Please find the debdiff attached.
Please download this package and install it. You should install it directly using dpkg and downgrade to the official package from stable immediately once the tests are over: https://people.debian.org/~fabian/jessie/libpoppler46_0.26.5-2+deb8u1.1_amd64.deb Then, please install the fonts-texgyre package again and see if the "mu" glyph on the test page you pointed to in your initial bug report renders properly. Please make sure that the text is rendered with the TeX Gyre OTF fonts. Also, while at it, could you please check if the PDFs pointed to in these bug reports render properly as well -- in Evince, that is, not in e.g. Iceweasel's integrated PDF viewer. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=773271 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=807693 Thank you so much! - Fabian
