hi I reinstalled fonts-texgyre
then I installed your package: ii libpoppler46:amd64 0.26.5-2+deb8u1.1 amd64 then I found out that neither atril not evince is linking against libpoppler by running ldd on those binaries. Some of my own software links against libpoppler and there i find your library. maybe evince is somehow loading libpoppler at runtime. or it does not use libpoppler! anyway. running atril or evince does not show the micro sign. cya erik
