U+1D73F
𝜿 is a Unicode math symbol: MATHEMATICAL BOLD ITALIC SMALL KAPPA (U+1D73F). It’s typically used when you need a kappa glyph in bold italic math styles. Use the copy options below to paste it reliably across apps and code.
Mathematical Bold Italic Small Kappa Symbol Meaning
𝜿 (U+1D73F) represents a styled lowercase kappa for mathematical typesetting. The “bold italic” aspect signals a specific visual treatment—useful in equations, vectors, or parameter notation where different typographic weight and slant are meaningful. In practice, 𝜿 is less common than the standard kappa (κ), so it’s mainly chosen to match a document’s existing math font styling. If you’re converting or recreating math text, using the exact Unicode character helps maintain consistent appearance across systems that support the glyph.
Common uses
- •Typing math variables that must appear as bold italic kappa in equation text
- •Maintaining consistent notation when copying styled math from documents or PDFs
- •Designing math-focused graphics or typography where kappa needs a specific weight and slant
- •Using the correct Unicode character in technical writing and equation labeling
- •Generating or transforming Unicode math strings in software localization and rendering
