Joining Group - Thin Yeh

Thin Yeh is a cursive joining behavior used in Arabic script variants, specifically for the letter Yeh when it appears in a thin or reduced form, often in final or isolated positions. This value indicates that the character connects to preceding letters but does not connect to following ones, creating a right‑joining pattern. It is typically applied to characters like the Arabic letter Yeh with a thin stroke, which occurs in certain orthographic traditions or typographic styles, such as in Persian or Urdu where the form differs from the standard thick Yeh. Thin Yeh ensures proper text shaping by preventing unwanted ligatures or connections, preserving readability and the intended visual distinction between similar‑looking letters.
