U+FEB6 "ﺶ" Arabic Letter Sheen Final Form Unicode Character

U+FEB6 "ﺶ" Arabic Letter Sheen Final Form is a presentation form of the Arabic letter sheen (ش), specifically designed for use in Arabic script when it appears at the end of a word, where it connects only to the preceding character. This glyph, which features three dots arranged in a triangle above a curved, final-position shape, is part of the Arabic Presentation Forms-B block and is primarily used in text rendering contexts where Unicode's standard bidirectional algorithm may require explicit positional forms for accurate typography. U+FEB6 represents a ligature variant that encodes the visual appearance of sheen in its isolated or final context, supporting proper shaping in complex scripts like Arabic, Persian, and Urdu, though modern Unicode processing typically relies on the base character U+0634 (ش) with automated glyph substitution.
