This character is a Math Symbol and is commonly used, that is, in no specific script.
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 mirrored into Double Subset. The word that U+22D1 forms with similar adjacent characters prevents a line break inside it.
