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 Square Original Of. The word that U+228F forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.
