U+1D45F "𝑟" Mathematical Italic Small R Unicode Character
Unicode Version 18.0
Source: Browser Default
U+1D45F "𝑟" Mathematical Italic Small R is a typographic variant of the Latin letter "r" specifically designed for mathematical and scientific notation, where it serves distinct roles separate from its standard italic form. It is part of the Mathematical Alphanumeric Symbols block, enabling authors to differentiate mathematical variables from regular text, particularly for operations like correlation coefficients, growth rates, or geometric radii. This character ensures precise rendering in digital typesetting, avoiding ambiguity when a mathematician or researcher needs an italic "r" that is explicitly recognized as a mathematical symbol by software and fonts supporting Unicode.
