U+1D44F "𝑏" Mathematical Italic Small B Unicode Character
Unicode Version 17.0
U+1D44F "𝑏" Mathematical Italic Small B is a typographic variant of the Latin letter "b" that is designed specifically for mathematical and scientific text, where it represents a variable, constant, or parameter in a slanted, italicized form distinct from the upright letter used in regular prose. This character belongs to the Mathematical Alphanumeric Symbols block, which provides a wide range of styled letters and digits to allow clear differentiation between symbols in equations, such as distinguishing a variable from a unit or a function name. By using this dedicated codepoint, authors and software can ensure consistent rendering and semantic meaning, avoiding the ambiguity that might arise from relying on font-based italic styling applied to a standard "b".
