U+FDF8 "ﷸ" Arabic Ligature Wasallam Isolated Form Unicode Character

Unicode Version 17.0

U+FDF8 "ﷸ" Arabic Ligature Wasallam Isolated Form is a typographic ligature used in Arabic script to represent the common Islamic honorific phrase "صلى الله عليه وسلم" (Sallallahu Alayhi Wasallam), which means "peace be upon him" and is traditionally invoked after the name of the Prophet Muhammad. This character is encoded as a single glyph in the Unicode standard's Arabic Presentation Forms-A block, intended for compatibility with legacy document formats that display the entire invocation as a distinct visual symbol rather than separate sequential letters. It is primarily used in religious texts, calligraphy, and digital typography to economize space and preserve conventional scribal traditions, though modern usage strongly prefers standard Unicode-compliant text encoding over such precomposed ligatures for better accessibility and searchability.
