Joining Group - Gamal

Gamal is a value that defines the shaping behavior of the Arabic letter seen in forms like ج, particularly in connected scripts. It indicates that this character belongs to a specific joining group, meaning it connects to adjacent letters on both sides in a cursive text, typically with a downward tail in its initial and medial forms. The group ensures that when the letter appears in words, it joins correctly with preceding and following characters, maintaining the expected visual flow without taking on alternate isolated or final forms unexpectedly. This value helps renderers apply the right glyph variants, especially in languages like Arabic, Persian, and Urdu, where contextual shaping is essential for legibility and proper word formation.
