Description sergio.callegari 2017-01-01 23:48:13 UTC 
I have an issue with viewing a PDF file on poppler based viewers.

Please check

https://asp.eurasipjournals.springeropen.com/articles/10.1186/s13634-016-0326-2

and click the "Download PDF" button to get the critical file. It is an open access scientific paper, so it should be downloadable by everybody.

If I open the file with KDE Okular on Linux, poppler 0.44 gets used for the rendering on my system.

For the file specified above, starting from page 3 I have many missing chars, including: the "minus" sign (e.g., eqn. 3); the "in" sign (e.g., inline formula right below eqn. 6); the "less than" sign (e.g., eqn. 9), and so on.

All the missing chars seem to be on math fonts.

Interestingly:

- Mozilla's pdf.js displays everything correctly.
- Adobe reader, Foxit reader, MasterPDFeditor show some of the chars that are missing with poppler, but still miss some other chars (such as the minus sign).

That PDF renders fine for me in both – FF build in PDF viewer and Okular 1.3.1. Please retest and close if it renders fine now.

Tested with:
poppler-0.62.0-r1
poppler-data-0.4.8
Gentoo ~AMD64

Yes, seems to be OK now. Tested on kubuntu 17.10.
