Bug Description
[ Description ]
Some ligatures (e.g. "fi") are not displayed in certain fonts, because there are two different naming schemes in use in the wild.
[ Fix ]
Poppler upstream fixed this by adding a lookup table to fall back to the second scheme if necessary.
[ QA ]
1. Install tex-gyre
2. Download https:/
3. Open the file in evince
4. Look at "Biometrics: file" on page 3
If the "fi" ligature in "file" is not displayed, you have this bug. "file" should be displayed normally after it's fixed.
[ Regression potential ]
Since this patch implements a fallback only when lookup false, there shouldn't be any problems. Still, check all existing PDFs are still displayed correctly.
[ Original report ]
While there's Bug #1325230 with the same title and the linked PDFs there are working fine here (displaying "fi" correctly) there seems to be still some bug regarding ligatures.
https:/
I have some PDFs substituting Helvetica (and others) with TeX Gyre Heros and showing no "fi" ligature. I attached a patch I derived from the patch in Bug #1325230 which is working fine. Now it uses Nimbus Sans L and the ligatures are fine.

To make it clearer: Bug #1379375 treats TeX Gyre Termes, while this one treats TeX Gyre Heros. (Termes vs. Heros)
