 > Unfortuantly, I think that we can not fix this issue. The cause is the
 following: there are so many Arabic fonts (1000s) but unfortuantly most of
 them are decorated ! This mean that most of them are useless to our issue
 because they make it more un-approperiat. Also, the convenent Arabic fonts
 that can make display of site O.K are the following:
 >
 > - Arial (default fonts used by site itself = it's real font)
 >
 > - Time new roman
 >
 > - Arabic transparent
 >
 > - Simplified Arabic

 > All of above 4 fonts are not free in terms that needed so as to be
 included in Tor !!

 I want to thank you for taking the time to test so many fonts.

 How about the fonts at https://ar.wikipedia.org/, are they they same (bad)
 as on your sample page? Or does it look okay? Wikipedia also seems to be
 using `font-family: sans-serif, Arial`.

 I wonder, is it a difference between Naskh and Kufi scripts? To me, the
 Kufi version looks more "sans-serif" (perhaps a better match for Arial).

 Tor Browser contains NotoNaskhArabic-Regular.ttf but not NotoKufiArabic-
 Regular.ttf. If it really makes pages look better, we could consider
 adding NotoKufiArabic-Regular.ttf.
