U+1D492 "𝒒" Mathematical Bold Italic Small Q Unicode Character

Unicode Version 17.0

𝒒

U+1D492 "𝒒" Mathematical Bold Italic Small Q is a specific glyph belonging to the Mathematical Alphanumeric Symbols block, designed for use in scientific and mathematical typesetting to represent a variable or scalar quantity in a bold italic style. This character is part of a comprehensive set of stylized Latin letters that allow authors to visually distinguish mathematical variables from standard text, with the bold italic form often indicating a vector or a tensor in fields such as physics and linear algebra. Unlike simply applying bold and italic formatting to a standard lowercase q, U+1D492 is a distinct code point that ensures consistent rendering across different fonts and software. It can be typed directly in documents that support Unicode, but is typically not found on standard keyboards and is instead inserted via character maps, HTML entities like `𝒒`, or LaTeX commands such as `oldsymbol{q}`.
