Default [Q] which file is the "font encoder" on android.

I get a new phone a month ago.
(tronsmart TS7 - mtk6582)
and in some place the hebrew language (my longuage) doesn't render
for example:

when I port a rom from another MTK6582 phone (W450) the font was perfect, but a lot other thing was a mess (cam,GPU driver/codec)

and I try to replace font.... still same problem

my Q is with file is the one that make this "render" so I can port just this file from the other phone rom?
