Joining Group - Zhain

Zhain is a joining group that defines how the Arabic letter corresponding to the Persian and Urdu character for the “zh” sound (as in “vision”) connects to adjacent letters within a word. It belongs to the set of cursive script behaviors where letters can have initial, medial, final, or isolated forms depending on their position. Specifically, Zhain behaves like most Arabic letters, requiring a right-to-left connection, meaning it joins with the preceding character but does not connect to the following one, creating a break in the cursive flow. This affects shaping in text rendering, ensuring that words containing this letter are displayed correctly with proper ligatures and spacing. Its pattern aligns with other similar letters like zain and reh, but it retains its distinct identity for accurate typographic representation.
