U+1E03 "ḃ" Latin Small Letter B with Dot Above Unicode Character
Unicode Version 17.0
ḃ
U+1E03 "ḃ" Latin Small Letter B with Dot Above is a precomposed character primarily used in certain Latin-based orthographies, such as the older Irish orthography for the séimhiú (lenition) in transcription, where it represents a b sound that has undergone a phonological change often realized as a v-like sound. It is formed by combining the base Latin letter B with a combining dot above, and in modern Irish, it has largely been replaced by the digraph "bh" outside of specific phonetic or scholarly contexts. This glyph belongs to the Latin Extended Additional block and is distinct from characters with other diacritics, serving a specialized but meaningful role in the accurate representation of historical or dialectal written forms.
