U+1E02 "Ḃ" Latin Capital Letter B with Dot Above Unicode Character
U+1E02 "Ḃ" Latin Capital Letter B with Dot Above is a specialized letter used primarily in older or scholarly transcriptions of certain languages, such as medieval Irish, where the dot above the B indicates a lenited or mutated pronunciation, often representing a voiced bilabial fricative sound. This character is part of the Latin Extended Additional block in the Unicode standard and is distinct from the plain capital B by the addition of a combining dot above diacritic. It may also appear in phonetic notations or transliterations of other languages where a modified B denotes a specific articulatory feature. The lowercase counterpart is U+1E03 "ḃ", and this letter should not be confused with similar characters like the Latin capital letter B with dot below or other diacritic variants.
