U+1D530 "𝔰" Mathematical Fraktur Small S Unicode Character

Unicode Version 17.0

𝔰

U+1D530 "𝔰" Mathematical Fraktur Small S is a typographic letter derived from the Fraktur style of blackletter script, and it belongs to the Mathematical Alphanumeric Symbols block, which was introduced in Unicode version 3.1 to support mathematical notation. This character is specifically designed for use in mathematical and scientific texts where a distinct, ornate appearance is needed to differentiate variables or constants from standard italic or roman letters. Its form mimics the medieval German blackletter tradition, and it is commonly employed in fields such as set theory, logic, and abstract algebra to represent specific mathematical objects like ideals or algebras. By encoding this symbol separately from regular Latin letters, Unicode allows for precise and consistent rendering across different digital platforms and fonts.
