U+1D493 "𝒓" Mathematical Bold Italic Small R Unicode Character
Unicode Version 17.0
U+1D493 "𝒓" Mathematical Bold Italic Small R is a typographic symbol belonging to the Mathematical Alphanumeric Symbols block, designed specifically for use in mathematical and scientific notation to represent a variable or scalar in a bold italic style. This character is part of a larger set of over a thousand specialized letterforms that allow mathematicians, physicists, and engineers to clearly distinguish between different types of variables, vectors, and constants in printed equations. Its bold italic appearance combines the emphasis of bold weight with the slant of italic, commonly used to denote a vector quantity or a specific mathematical entity in fields like linear algebra or physics. While visually similar to an ordinary bold italic "r" in many fonts, its encoding as a distinct Unicode character ensures that it is recognized as a mathematical symbol rather than a stylistic variant of the Latin letter, preserving semantic meaning across different software and platforms.
