The issue seems to be that the Termes font uses the wrong name for the
fi and fl ligatures. See comment 7

https://bugs.freedesktop.org/show_bug.cgi?id=73291#c7

I am not sure if it the responsibility of the render (poppler) to map
both fi and f_i to the same glyph. Apparently there was some
uncertainty if this is a poppler bug
(https://bugs.freedesktop.org/show_bug.cgi?id=73291#c14) but
eventually was marked as being an issue with the font (last comment
https://bugs.freedesktop.org/show_bug.cgi?id=73291#c17 ).

According to the comments in there the ligature shows up in gv since
gv prefers the gsfonts fonts over gyretex.

Yours,
Roland
