U+FE7C "ﹼ" Arabic Shadda Isolated Form Unicode Character

Unicode Version 17.0

ﹼ

U+FE7C "ﹼ" Arabic Shadda Isolated Form is a presentation form variant of the standard Arabic diacritical mark shadda, which indicates consonant gemination or doubling in Arabic script. Unlike the regular combining shadda that appears directly over a base letter, this isolated form is intended for use in certain typographic or legacy text rendering contexts where markers appear separately from their associated letters, such as in historical fonts or specific digital encoding schemes. It belongs to the Arabic Presentation Forms-B block, which contains characters designed to support complex text layout and compatibility with older systems, and its usage in modern Arabic writing is typically discouraged in favor of the standard combining shadda.
