Mathematical Sans-Serif Small K 𝗄
Visual Description: The character is a small k in a sans-serif style. It has a simple straight stem and a diagonal arm. The line width is even, with no decorative feet. In formula editors and calculators, it looks like the other sans letters. It fits cleanly with bold mathematical text.
Meaning & Usage: In math, this small k often stands for a variable, index, or parameter. It can denote a coefficient or a k-th element in a sequence. Sans-serif styling signals a non-italic variable in a UI that mixes fonts. Use it consistently with other letters in the same set.
Historical Background: The symbol belongs to a family of mathematical alphanumeric symbols chosen for digital math. The goal was to provide consistent, readable letters for software, calculators, and web math. The sans-serif variants help separate math variables from body text. The approach is general and non-specific in tone.
Practical Use: Use this k in formulas, sums, and equations displayed on calculators or in software. It can represent a coefficient, an index, or a constant. UI controls like sliders or stepper buttons can adjust k quickly, and operators can compare k to other values in real time.

HTML: use the numeric entity 헄 (hex) or 헄 (decimal) when an HTML entity is needed.
Compatibility & troubleshooting
Font support: if the symbol does not render, the current font likely lacks this codepoint. Choose a font with broad Unicode coverage or allow a fallback font.
Web pages: ensure your CSS font stack includes a general fallback; avoid relying on images for common symbols to preserve accessibility and copyability.
