U+0181 "Ɓ" Latin Capital Letter B with Hook Unicode Character
Unicode Version 17.0
Ɓ
U+0181 "Ɓ" Latin Capital Letter B with Hook is a modified version of the standard Latin letter B, distinguished by a small hook attached to the bottom right of its stem. This character is primarily used in the orthographies of several African languages, including Hausa, Bissa, and Fula, where it represents a voiced bilabial implosive consonant sound. It is also employed in the International Phonetic Alphabet as an official symbol for this specific phonetic feature, though it remains distinct from the standard IPA usage that often employs a lowercase variant for typographical consistency.
