U+FEBF "ﺿ" Arabic Letter Dad Initial Form Unicode Character

Unicode Version 17.0

ﺿ

U+FEBF "ﺿ" Arabic Letter Dad Initial Form is a contextual variant of the Arabic letter Ḍād (ض), specifically designed to appear at the beginning of a word when connected to a following character within cursive Arabic script. Rendered as a bold, sweeping shape with a prominent loop and a rightward connecting stem, this initial form differs visually from the isolated (ﻀ) and medial/final forms of the same letter, ensuring proper typographic flow in connected text. It represents the emphatic consonant /dˤ/, a distinctive sound in Arabic phonology, and is used in words like "ﺿﺮﻭﺭﻱ" (ḍarūrī, meaning "necessary"), where it appears as the first character before the letter ر (rāʾ). This glyph is part of the Arabic Presentation Forms-B block in Unicode, encoding a positional variant that is essential for accurate digital rendering of Arabic script.
