When to use it

κ writes U+03BA (Greek Small Letter Kappa), 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 dates from HTML 4, so it works in every browser and in old email clients.
