U+0183 "ƃ" Latin Small Letter B with Topbar Unicode Character

Unicode Version 17.0

ƃ

U+0183 "ƃ" Latin Small Letter B with Topbar is a visually modified form of the standard lowercase letter b, featuring a horizontal bar added to its top. This character is primarily used in the Latin-based orthography of several African languages, including the Mfumte language of Cameroon, where it represents a specific bilabial or labialized consonant sound distinct from the plain "b". Historically, it also appears in older Latin phonetic alphabets and in certain scholarly transcriptions of indigenous languages, where the topbar indicates a modified articulation or a fricative variation. As part of the Latin Extended-B block in Unicode, it serves as a practical tool for linguists and communities working to accurately encode and preserve non-European languages.
