Greetings!

I was considering working on some improvements for the font and I noticed it is licensed under GPLv2.

GPLv2 while being great license for software, can be a bad choice for fonts, since it can imply unintended restrictions or legal consequences and uncertainties for people using the font.

The consensus in the FOSS community seems to be, to go with the SIL Open Font License, which is a FOSS license specially designed for fonts :)

It is OSI & FSF approved and Copyleft, too.

I think that would be a good move unless you have some specific reason to stick with GPLv2 for the font @hisham :)

EDIT: I researched a bit and found this page https://fontsarena.com/licenses-explained/
It seems MIT license or one of the CC licenses are also good choices.
So depends on what you would like to go with. MIT would be even less restrictive :)
