Glyph for U+22C2
Source: Noto Sans Math
U+22C2 N-Ary Intersection
U+22C2 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 character is also known as z notation generalised intersection .

The glyph is not a composition . It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral . When changing direction it is not mirrored . The word that U+22C2 forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph .

The CLDR project calls this character “n-ary intersection” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: intersection, mathematics, set operator.

The Wikipedia has the following information about this codepoint:

In set theory, the intersection of two sets $A$ and $B,$ denoted by $A\cap B,$ is the set containing all elements of $A$ that also belong to $B$ or equivalently, all elements of $B$ that also belong to $A.$
