Joining Group - Manichaean Samekh

Manichaean Samekh is a joining group value that defines how the Manichaean letter Samekh connects to adjacent letters in scripts that use cursive or connected writing systems. It specifies that this particular character belongs to a group that shares identical joining behavior, meaning it connects in a specific, predictable way to both preceding and following characters, typically forming a rightward link while maintaining a distinct form. This grouping ensures that when the letter appears in text, its contextual shapes are rendered consistently across fonts and applications, preserving the script’s visual integrity. The value is essential for correctly shaping words in Manichaean, where letters change form based on their position in a word, and it works alongside similar values for other letters to enable seamless text shaping.
