Glyph for U+222D
Source: Noto Sans Math

U+222D Triple Integral

U+222D was added in Unicode version 1.1 in 1993. It belongs to the block U+2200 to U+22FF Mathematical Operators in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Math Symbol and is commonly used, that is, in no specific script.

The glyph is a compatibility composition of the glyphs Glyph for U+222B Integral, Glyph for U+222B Integral, Glyph for U+222B Integral. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is mirrored. The word that U+222D forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.

The Wikipedia has the following information about this codepoint:

In mathematics (specifically multivariable calculus), a multiple integral is a definite integral of a function of several real variables, for instance, f(x, y) or f(x, y, z). Physical (natural philosophy) interpretation: S any surface, V any volume, etc.. Incl. variable to time, position, etc.

Integrals of a function of two variables over a region in R2 (the real-number plane) are called double integrals, and integrals of a function of three variables over a region in R3 (real-number 3D space) are called triple integrals. For multiple integrals of a single-variable function, see the Cauchy formula for repeated integration.
