Joining Group - Farsi Yeh

Farsi Yeh is a joining group that defines how the Arabic letter Yeh, as used in Persian and other languages, connects to adjacent characters in cursive script. It specifically represents the form of Yeh that retains its two dots below the baseline, distinguishing it from the standard Arabic Yeh, which lacks those dots in certain contexts. In joining behavior, Farsi Yeh acts like a dual-joining character, meaning it can connect to both the preceding and following letters, but its isolated and initial forms appear with a distinct curved tail that often slopes downward. This group ensures that text rendering software correctly shapes the letter when it appears in words like “Iran” or “Farsi,” maintaining legibility and proper visual continuity. It is particularly important for scripts that use Persian orthography, such as Urdu and Kurdish, where the dotted form is essential to avoid confusion with other letters.
