Unicode Version 17.0
𝛨
U+1D6E8 "𝛨" Mathematical Italic Capital Eta is a glyph from the Mathematical Alphanumeric Symbols block, designed to represent the Greek letter eta (Η) in an italic style for use in mathematical and scientific notation. It is distinct from the regular Greek capital eta or the Latin H, enabling writers to differentiate variables, constants, or specific terms in equations, particularly in contexts like physics, engineering, or advanced mathematics where italicized Greek letters are standard for denoting quantities such as efficiency, viscosity, or the eta function.
