U+FDF9 "ﷹ" Arabic Ligature Salla Isolated Form Unicode Character

Unicode Version 17.0

U+FDF9 "ﷹ" Arabic Ligature Salla Isolated Form is a typographic ligature used in Arabic script to represent the Arabic word "صلى" (salla), meaning "he prayed" or "may blessings be upon," often appearing in religious contexts such as invocations for the Prophet Muhammad. This character is encoded in the Unicode standard as part of the Arabic Presentation Forms-A block, which contains specialized ligatures and contextual forms for advanced text rendering. Its primary function is to display the word in a compact, calligraphic style when used in isolation, preserving the traditional appearance of Arabic calligraphy in digital text. However, in modern practice, its usage is limited as standard Unicode Arabic characters and font shaping are generally preferred for flexibility and compatibility across different systems.
