U+2A19 "⨙" Integral with Intersection Unicode Character
Unicode Version 17.0
U+2A19 "⨙" Integral with Intersection is a mathematical symbol found in the Supplemental Arrows‑C and Supplemental Mathematical Operators block, designed for use in advanced notation, particularly in set theory and measure theory, to represent integration over an intersection of sets. It combines the classic integral sign with a intersecting cap‑like symbol, indicating that the integration domain is the intersection of two or more sets, often in contexts like integrating over the overlap of measurable regions. This character is part of a family of specialized integral symbols that accommodate nuanced mathematical expressions in digital text, though it may not be supported by all fonts or rendering systems. Its Unicode designation ensures consistent encoding across platforms, facilitating precise communication in academic and technical documents.
