Public bug reported: In some PDF files, characters like hyphen (minus sign) and others symbols are not printed in Evince.
According to https://bugs.freedesktop.org/show_bug.cgi?id=94615, the bug is in version 1.14 of cairo. The bug was fixed last year in version 1.15 (see https://cgit.freedesktop.org/cairo/commit/?id=190678f6444ad879847d603c3c9eaf8e9ab6887a). I've backported the above patch in Ubuntu 16.04 xenial, and it fixes the bug. To reproduce the bug (see attached test files) in Ububtu 16.04 (with libcairo2 1.14.6-1): 1. Create a LaTeX test document (test.tex) with the following content: \documentclass{article} \usepackage[T1]{fontenc} \begin{document} a-b--- \end{document} 2. Create a test.pdf from test.tex: pdflatex test.tex 3. Create a cairo pdf output (or print test.pdf on a printer, using Evince): pdftocairo test.pdf -pdf test1.pdf Open test1.pdf with Evince: as you can see, some of the hyphen signs have disappeared. To fix the bug, rebuild the cairo deb packages with the attached patch, install the packages and do (or print test.pdf on a printer, using Evince): pdftocairo test.pdf -pdf test2.pdf Now, open test2.pdf with Evince: there is no more missing hyphen sign.
