U+068E "ڎ" Arabic Letter Dul Unicode Character

U+068E "ڎ" Arabic Letter Dul is a variant of the Arabic letter ḏāl, specifically used in certain languages of Africa and South Asia, such as the Berber languages of Algeria and the Arabic script for Balochi, to represent a voiced dental or alveolar fricative similar to the "th" in "that". It is encoded in the Unicode Standard under the Arabic block, where it serves as a distinct glyph from the more common ḏāl (ذ) and is employed to accurately transcribe phonetic distinctions not present in standard Arabic. The character’s visual form consists of a curved base with a loop and a dot above, reflecting its role in extending the Arabic alphabet to accommodate non-Arabic sounds in writing systems that use an extended Arabic script.
