This ligature is used in certain styles of Arabic calligraphy and typesetting to facilitate fluid and aesthetically compact text, particularly in historical or decorative scripts where such combinations follow traditional orthographic conventions. It is important to note that this character is a presentation form intended for specific visual rendering rather than a standard grapheme used in modern Arabic writing, and its implementation depends on font support and rendering engines that can properly display this specialized ligature.
