Unicode Version 17.0

𝓚

U+1D4DA "𝓚" Mathematical Bold Script Capital K is a stylized letter variant included in the Mathematical Alphanumeric Symbols block, designed for use in scientific and mathematical typesetting to distinguish variables or constants from plain text. Its design merges a bold weight with a flowing, cursive script style, making it visually prominent in equations, formal proofs, or symbolic notation where a distinctive capital K is needed. This character is typically rendered in specialized fonts like Cambria Math or Latin Modern Math, and it is often employed in fields such as calculus, linear algebra, or mathematical physics to represent sets, matrices, or named constants like Kelvin in thermodynamic contexts. Codified in Unicode version 3.1 in 2001, it ensures consistent representation across digital platforms for mathematical communication.
