Unicode Version 17.0
𝘽
U+1D63D "𝘽" Mathematical Sans-Serif Bold Italic Capital B is part of the Mathematical Alphanumeric Symbols block, designed to provide a distinct, stylized version of the uppercase letter B for use in mathematical and scientific notation. This character combines a sans-serif typeface with bold weight and italic slant, allowing it to represent variables, vectors, or set elements in contexts where a plain Latin letter might be ambiguous or insufficient for distinguishing semantic roles. It is not intended for ordinary text, but rather for precise, technical communication in fields like algebra, physics, or computer science.
