First I know there are similar questions to mine,
and I do tried Font Squirrel Generator for tons of Arabic fonts, all of them render text in Englis
Switch the Font Squirell to Expert mode.
Then on Subsetting: choose either No subsetting or Custom subsetting
No subsetting
Custom subsetting
Sorted! :)
EDIT:
On custom subsetting you either need to tick your desired subset or type it in the input fields.
