Unicode Version 17.0

𝛶

U+1D6F6 "𝛶" Mathematical Italic Capital Upsilon is a typographic variant of the Greek letter Upsilon, designed specifically for use in mathematical and scientific notation where variables, constants, or operators need to be distinguished from standard text. It belongs to the "Mathematical Alphanumeric Symbols" block, which provides italic forms of Greek letters to match the style of italic Latin letters commonly found in equations. This character is fundamentally different from a simple italicized Greek letter in regular fonts, as it carries a unique codepoint to ensure consistent rendering across digital platforms and documents. It is typically used to represent physical quantities, such as in particle physics for the Upsilon meson, or as a symbol in other technical fields to avoid confusion with non-mathematical text.
