A connected typeface design with a calligraphic flavor. The Lahab (Arabic for flame) font family employs visual features from the Arabic Diwani Calligraphy. It has six members, normal, bold, and light, all of which come in two styles, regular and left-slanted italic styles. This font family design follows the guidelines of Mutamathil Taqlidi type style with one glyph for every basic Arabic Unicode character or letter, as defined in the latest Unicode Standards, and one additional final form glyph, for the freely-connecting letters in traditional Arabic cursive text. Lahab employs variable x-height values. It includes only the Lam-Alif ligatures. Soft-vowel diacritic marks, harakat, are selectively positioned. Most of them appear by default on the same level, following a letter, to ensure that they would not interfere visually with letters. Tatweel is a zero-width glyph. Keying the tatweel key before Alif-Lam-Lam-Ha will display the Allah ligature. Lahab includes both Arabic and Arabic-Indic numerals, in addition to standard punctuations.
