U+1D6EA "𝛪" Mathematical Italic Capital Iota Unicode Character

Unicode Version 17.0

𝛪

U+1D6EA "𝛪" Mathematical Italic Capital Iota is a glyph from the Mathematical Alphanumeric Symbols block, designed for use in scientific and mathematical notation to represent the Greek letter iota in an italic typeface. It belongs to a comprehensive set of italic Greek letters intended to match the style of italic Latin letters in mathematical expressions, ensuring visual consistency when denoting variables, constants, or units such as the imaginary unit in contexts where a distinct, non-oblique Latin i might cause confusion. This character, encoded as part of the larger initiative to separate mathematical symbols from ordinary text, allows authors and formula typesetters to clearly indicate the semantic role of iota as a mathematical entity rather than a typographic variant.
