U+1D705 "𝜅" Mathematical Italic Small Kappa Unicode Character

Unicode Version 17.0

𝜅

U+1D705 "𝜅" Mathematical Italic Small Kappa is a typographic variant of the Greek letter kappa, specifically designed for mathematical and scientific notation where italic style is conventional for variables. It belongs to the “Mathematical Alphanumeric Symbols” block, allocated to distinguish it from the ordinary Greek small kappa (κ, U+03BA) in contexts such as tensor calculus, differential geometry, or fluid dynamics, where it may represent curvature, thermal conductivity, or the von Kármán constant. This encoding allows authors and typesetting systems to preserve both semantic meaning and desired formatting, ensuring that italic kappa appears distinct from other mathematical symbols and ordinary Greek text in digital documents and web content.
