U+0257 "ɗ" Latin Small Letter D with Hook Unicode Character

U+0257 "ɗ" Latin Small Letter D with Hook is a letter used primarily in the International Phonetic Alphabet to represent a voiced alveolar implosive, a type of consonant sound where the glottis moves downward while the tongue blocks the airstream. It appears in the orthographies of several African languages, such as Hausa and Fulani, where it denotes a distinct phoneme separate from the plain "d". The character is formed by adding a rightward hook to the top of a lowercase "d", and it is encoded in the Latin Extended B block of Unicode. This symbol is essential for accurate linguistic transcription and the proper representation of certain languages in digital text.
