...Thanks to DejaVu Sans font (v2.35) published in public domain there was a free software base to start the Vazir project. Although Vazir was completely different in typeface, still the original software was common. The design is done in Fontforge. For Latin glyphs, Vazirmatn is combined with Roboto font by a build script, however, there is also a version without Latin glyphs (Non-Latin). All weights other than Thin, Regular and Black are generated by the interpolation method by fontmake library.
