About this character

U+222E (∮) is CONTOUR INTEGRAL, a mathematical symbol in the Mathematical Operators block. Its script is Common: it is shared by many writing systems rather than belonging to one. It was added in Unicode 1.1 (1993).

It is a mirrored character: in right-to-left text renderers draw its mirror image.

Its East Asian Width is Ambiguous: it takes one column in Western contexts and two in East Asian legacy contexts, a common cause of misaligned tables in terminals.
