This character is a Math Symbol and is commonly used, that is, in no specific script.
The glyph is a canonical composition of the glyphs Succeeds, Combining Long Solidus Overlay. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is mirrored into Does Not Precede. The word that U+2281 forms with similar adjacent characters prevents a line break inside it.
The CLDR project calls this character “does not succeed” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: does, mathematics, not, operator, set, succeed.
The Wikipedia has the following information about this codepoint:
In mathematical notation, ordered set operators indicate whether an object precedes or succeeds another. These relationship operators are denoted by the unicode symbols U+227A-F, along with symbols located unicode blocks U+228x through U+22Ex.
