Harmattan, named after the trade winds that blow during the dry season in West Africa, is designed in a Warsh style to suit the needs of languages using Ajami (the Arabic script) in West Africa. The font was originally designed specifically for languages in Guinea. Significant design changes have been made as the font has been extended to handle a wider variety of languages using the Arabic script. The font features are easily configurable to select regional styles of glyphs.
Harmattan is considered highly legible and has been used in mobile applications for languages in other regions of the world.
The Harmattan font family consists of four weights: Regular, Medium, SemiBold, Bold.
