U+FB84 "ﮄ" Arabic Letter Dahal Isolated Form Unicode Character

U+FB84 "ﮄ" Arabic Letter Dahal Isolated Form is a typographic variant of the Arabic letter دال (dal) found within the Arabic Presentation Forms-B block, where it represents an isolated contextual form used primarily for calligraphic or historical text rendering and compatibility with legacy fonts. This particular form, known as "dahal," is not a standard modern Arabic letter but appears in certain Persian or extended Arabic scripts to denote a retroflex or emphatic d sound, often in languages like Urdu or Pashto. Its isolated shape, written as a standalone glyph, is designed to appear when the character occurs alone or after a non connecting letter, preserving the elegant cursive style of Arabic script without joining to any subsequent character.
