Unicode Version 17.0

𝟩

U+1D7E9 "𝟩" Mathematical Sans-Serif Digit Seven is a typographic variant of the digit seven, designed with a clean, stroke-based sans-serif style distinct from the serif forms found in standard text fonts. It belongs to the Mathematical Alphanumeric Symbols block, which provides distinct characters for use in mathematical notation where specific font styles, such as sans-serif, carry semantic meaning. This particular digit is identical in value to the regular digit 7 but is intended for contexts like variable names, equations, or scientific documents to differentiate it from other symbols or to match a consistent sans-serif style. As part of a unified set of digits, it ensures correct mathematical rendering across platforms and fonts that support this Unicode range.
