U+2A1A "⨚" Integral with Union Unicode Character

U+2A1A "⨚" Integral with Union is a mathematical symbol that combines the classic integral sign with the union operator, typically used in advanced set theory or measure theory to denote integration over a union of disjoint sets. Its design merges the elongated ‘S’ shape of the integral with a small cup-like union symbol placed as a subscript or modifier, clarifying that the integration domain is formed by combining multiple regions. This glyph is part of the Supplemental Mathematical Operators block, intended for precise notation in formal mathematics where standard integral symbols alone might be ambiguous.
