Adjusting word space for fonts/languages

So I’ve configured my system to work with non latin script languages with fonts that I want it to use, but the spacing between these fonts isn’t enough for clarity. To be specific, I’ve used the Jameel Noori Nastaleeq font for Urdu, a language using the Arabic script, and while the font itself works, there is barely any word spacing visible while using it. Is there a way to fix this?

For reference, I’m using KDE Plasma.
