When to use it

ϰ writes U+03F0 (Greek Kappa Symbol), a small letter from the Unicode Greek and Coptic block, encoded since Unicode 1.1. In mathematics, single Greek letters are usually set in italic; MathML or a maths font handles that automatically.

The name comes from the HTML5 list (much of it shared with MathML), so it works in every current browser but not in XML or XHTML served as XML, where the numeric reference is the safe choice.
