U+1D779 "𝝹" Mathematical Sans-Serif Bold Small Kappa Unicode Character

U+1D779 "𝝹" Mathematical Sans-Serif Bold Small Kappa is a typographic glyph used in mathematical notation to represent the Greek letter kappa in a sans-serif, bold typeface, which helps distinguish it from other variables or constants in equations. It is part of the Mathematical Alphanumeric Symbols block, designed for use in scientific and technical texts where precise style differentiation is required, such as in physics, engineering, or linear algebra. This character allows authors to denote a specific variant of the kappa symbol without relying on font formatting that might not transfer reliably across different systems or documents.
