U+2A4C "⩌" Closed Union with Serifs Unicode Character
Unicode Version 17.0
⩌
U+2A4C "⩌" Closed Union with Serifs is a mathematical symbol used in set theory and logic to represent a union operation where the typical U-shaped cup is closed off with small, squared serifs at its two upper terminals, giving it a more structured or seriffed appearance. This glyph is part of the Supplemental Mathematical Operators block and is distinct from the standard union symbol by its formal, bracketed look, which can help denote a variant union in certain typefaces or notations, though it is not widely used in everyday mathematics. Its inclusion in Unicode ensures that specialized documents can precisely represent this nuanced operator without relying on custom fonts or approximate substitutes.
