Janna is an Arabic variant designed by Nadine Chahine, based on the original Avenir. Janna, which means "heaven" in Arabic, was first designed in 2004 as a signage face for the American University of Beirut. The Arabic glyphs are based on the previously released Frutiger Arabic, but were made more angular.
Two roman fonts, in regular and bold weights, were produced. The typeface supports ISO Adobe 2, Latin Extended, Arabic, Persian, and Urdu characters, and tabular numerals for the supported languages.
Nadine Chahine graduated from the American University of Beirut with a degree in graphic design, and during her studies there she became interested in Arabic typography. In 2003 she received a master's degree in typeface design from the University of Reading, where she studied under Gerard Unger and the renowned French type designer Jean François Porchez. While studying there, she concentrated on congruous relationships between Latin and Arabic scripts.
Her typefaces include Koufiya (a dual-script font family, Latin and Arabic), Arabic versions of Latin typefaces, such as Frutiger Arabic, Neue Helvetica Arabic, and Palatino Arabic, as well as new Arabic fonts, including Janna and Badiya.
