U+1D4B3 "𝒳" Mathematical Script Capital X Unicode Character
Unicode Version 17.0
U+1D4B3 "𝒳" Mathematical Script Capital X is a stylized, cursive representation of the uppercase letter X, belonging to the Mathematical Alphanumeric Symbols block and encoded for use in scientific and mathematical notation where a distinct, often elegant script form is needed to differentiate variables from standard text. It is part of a larger set of script letters (Mathematical Script and Fraktur) used to represent specific mathematical objects such as sets, tensors, or special functions, and it should not be confused with the regular Latin capital X or with the similarly shaped script X in other fonts. Its visual design mimics a handwritten or calligraphic X, making it a typographically rich character employed in formal mathematical documents and digital typesetting systems like LaTeX via the mathcal{X} command.
