U+2A0E "⨎" Integral with Double Stroke Unicode Character

U+2A0E "⨎" Integral with Double Stroke is a mathematical symbol used in advanced notation, primarily within integral calculus and operator theory. Its design features the standard integral sign with an additional vertical stroke through its center, which distinguishes it from the common integral and often indicates a specific type of integral transformation, such as a path integral or a generalized integration operator in contexts like harmonic analysis or functional calculus. This symbol helps mathematicians and physicists denote operations that involve a double or iterated integration process, or a specialized operator over complex domains, without relying on extra subscript or superscript annotations.
