U+018B "Ƌ" Latin Capital Letter D with Topbar Unicode Character
Unicode Version 17.0
Ƌ
U+018B "Ƌ" Latin Capital Letter D with Topbar is a modified Latin letter used primarily in historical or phonetic transcription contexts, where a horizontal stroke across the top of the capital D indicates a specific sound variant or orthographic distinction. This character is part of the Latin Extended-B block and is the uppercase form of the lowercase "ƌ" (U+018C). Its function often relates to African languages or early linguistic notation systems, where the topbar serves as a diacritical marker to differentiate it from the standard Latin D. Due to its specialized usage, the glyph is not commonly found in everyday text but remains encoded for scholarly and typographic consistency in representing certain phonemes or historical scripts.
