Joining Group - Pe

Pe is a specific value within the Joining Group that identifies the Persian letter "pe" (also written as "be" with three dots below, U+067E). This group governs how the character connects to neighboring letters in cursive scripts like Arabic, Persian, and Urdu, particularly in determining its initial, medial, final, or isolated forms. Characters assigned to the "Pe" group, such as the Arabic letter with the same shape, share identical joining behavior, meaning they connect on both sides when in a word, except in specific contexts where their form changes due to preceding or following characters. The value ensures that shaping engines treat all members consistently, preserving the distinct visual identity of the sound /p/ in languages that use the script, while distinguishing it from the "Beh" group, which lacks the extra dots. This precise grouping is essential for correct text rendering and typographic layout in digital environments.
