Mathematical Bold Italic Small Epsilon Symbol Meaning
𝜺 (Unicode name: MATHEMATICAL BOLD ITALIC SMALL EPSILON, U+1D73A) is a typographic variant of the Greek letter epsilon used in math contexts. Unlike plain ε, this character encodes a “bold italic small epsilon” style, which can matter when your typography or document uses distinct weights and slants for variables. In practice, it’s most relevant for digital typography, publishing workflows, and Unicode-faithful math text where you want the exact glyph rather than relying on styling that may differ across fonts or platforms.
