Joining Group - Seen

Seen is a value that categorizes letters based on their shape and behavior in Arabic script, specifically referring to the letter seen (س). It defines how this character connects to neighboring letters, whether it joins on both sides, only the right, or stands alone, which affects the visual form of the word. This classification helps determine the correct presentation of the character in cursive text, ensuring that words render with the appropriate initial, medial, final, or isolated shape depending on its position. The group also includes related variant forms, such as those used in extended Arabic scripts, which share a similar structural design but may have slight differences in stroke or dot placement. By assigning a specific group, the system ensures consistent and accurate rendering across different fonts and languages that use Arabic-based writing systems.
