Languages like Arabic, Urdu, Pashto, Persian are the languages in which there exists one of the most profound works in the field of literature, science, math, etc. Most of these works have been translated but translation can never be equivalent to the original. Much of the essence is lost in translating.

But unfortunately the giant companies on the internet use poor and hard-to-read fonts for such languages.

Khushkhat is a nice add-on which lets you choose fonts for such languages, pretty nice and readable fonts.
