Joining Group - Yeh

Yeh is a joining group that defines how the Arabic letter yeh, along with its contextual variants, connects to adjacent characters in cursive scripts like Arabic and Syriac. It specifies a right-joining behavior, meaning the letter attaches to the preceding character but not to the following one, creating a distinct visual break in words. This group also encompasses forms such as farsi yeh and dotless yeh, which share similar connectivity rules but differ in shape or phonetic role. The value helps render text accurately by determining whether ligatures form or spaces remain between letters, crucial for proper typesetting and script shaping in digital environments. Its behavior is consistent across languages that use these letterforms, ensuring predictable text layout in both simple and complex writing systems.
