This is certainly a font bug, so GUST, not the developers, have to fix
their fonts.

Any how, the attached python script would fix that issue for any TeX
Gyre font, you'll need FontForge Python extension installed, run it on
the font:

./ffl_ffi.py font.otf

or you can run it on all .otf fonts in the current dir:

for i in *.otf; do ./ffl_ffi.py $i; done

And it'll create new fonts with the same name and .otf.otf extension,
replace old fonts with those and it should work (it does for me at
least).

 Khaled
