U+0689 "ډ" Arabic Letter Dal with Ring Unicode Character

U+0689 "ډ" Arabic Letter Dal with Ring is a modified letter used in the Arabic script to represent a retroflex or emphatic voiced dental stop, most prominently in the Pashto language, where it is pronounced as a hard or dark "d" sound distinct from the standard Arabic "د". It is formed by adding a small ring above the base letter "د" (dal), which serves as a diacritical mark to indicate this specific phonetic value. This character is part of the Arabic block in Unicode and is essential for correctly writing and reading Pashto orthography, as it appears in common words and names. Its inclusion in the standard ensures proper digital representation and typographic consistency for this significant regional variant of the Arabic script.
