some glyphs are clipped

[axidev]

the arabic letter "ي" has two dots at the bottom,
in chrome , firefox , and most other apps these two dots do'nt appear . and the line looks like it's cropped from bottom so the two dots do'nt appear
so it looks like this صيفى instead of صيفي
and شتوى instead of شتوي

in microsoft word , editpad appears correctly ,
I am using windows 10.
thanx
