U+1D535 "𝔵" Mathematical Fraktur Small X Unicode Character

Unicode Version 17.0

𝔵

U+1D535 "𝔵" Mathematical Fraktur Small X is a stylized variant of the standard Latin letter "x," drawn in the Fraktur script, a blackletter typeface historically used in German printing and mathematical notation. It resides in the Mathematical Alphanumeric Symbols block, which was introduced in Unicode version 3.1 to support specialized fonts in scientific and scholarly texts. This character is primarily employed in mathematics and formal logic to represent variables, sets, or algebraic elements, often to differentiate them from other symbols or to denote a specific theoretical construct within a document. Its ornate, gothic appearance helps avoid confusion with similar characters like the ordinary Latin "x" or the multiplication sign in densely symbolic expressions.
