U+1D5B7 "𝖷" Mathematical Sans-Serif Capital X Unicode Character

Unicode Version 17.0

𝖷

U+1D5B7 "𝖷" Mathematical Sans-Serif Capital X is a typographic variant of the Latin capital letter X, styled in a clean, sans-serif typeface without decorative serifs. It belongs to the Mathematical Alphanumeric Symbols block, a vast Unicode range designed to enable precise mathematical and scientific notation by providing distinct letterforms that avoid confusion with ordinary text. Unlike the standard "X" used in prose, this character is intended for use in equations, variables, and formulas where a sans-serif style is required or preferred for clarity. Its inclusion in Unicode allows mathematicians, scientists, and digital typesetters to represent abstract concepts or specific notational systems, such as those found in algebra, set theory, or physics, with a consistent and unambiguous glyph.
