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, n-ary, operator, set.
The Wikipedia has the following information about this codepoint:
In set theory, the intersection of two sets and denoted by is the set containing all elements of that also belong to or equivalently, all elements of that also belong to
