Problem with that font is they haven't pushed a new build of it in over a year. You can take their build file and build it with a newer Iosevka, but you'd have to learn how that tool works (I've done it, its not user friendly).

Might you rather be interested in https://github.com/ahatem/IoskeleyMono ?

Dude, word! I've been in love with Pragmasevka the moment a friend recommended it. Only thing to adjust is the `cell width` of your terminal.
