U+1D51B "𝔛" Mathematical Fraktur Capital X Unicode Character
Unicode Version 17.0
U+1D51B "𝔛" Mathematical Fraktur Capital X is a stylized letter derived from the blackletter or Fraktur script, a typeface historically associated with medieval German manuscripts and early modern printing. It is part of the Unicode Mathematical Alphanumeric Symbols block, designed for use in mathematical and formal contexts to distinguish variables, operators, or constants from standard Latin letters. This character represents a specialized glyph for the uppercase X, often employed in fields such as set theory, group theory, or logic to denote abstract mathematical objects or transformations. Its ornamental, angular appearance helps prevent confusion with the regular Latin X in dense symbolic notation while preserving the letter's fundamental identity.
