U+1D6C6 "𝛆" Mathematical Bold Small Epsilon Unicode Character

U+1D6C6 "𝛆" Mathematical Bold Small Epsilon is a typographic variant of the Greek letter epsilon, rendered in a bold typeface for use in mathematical notation. It is part of the Mathematical Alphanumeric Symbols block, which was introduced to allow authors to clearly represent variables, constants, and other mathematical concepts without relying on formatting workarounds. This bold epsilon is often used in fields such as set theory, calculus, and differential geometry to denote a small positive quantity, a member of a set, or a specific mathematical function, where the bold weight helps distinguish it from both italic and regular Greek letters. Its inclusion in Unicode ensures consistent display and proper semantic identification across digital platforms.
