        <pre>I have an issue with viewing a PDF file on poppler based viewers.

Please check

<a href="https://asp.eurasipjournals.springeropen.com/articles/10.1186/s13634-016-0326-2">https://asp.eurasipjournals.springeropen.com/articles/10.1186/s13634-016-0326-2</a>

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).</pre>
