U+220B was added in Unicode version 1.1 in 1993. It belongs to the block Mathematical Operators in the Basic Multilingual Plane.

The glyph is not a composition. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it acts as Other Neutral. When changing direction it is mirrored into Element Of. If its East Asian Width is “narrow”, U+220B forms a word with similar characters, which prevents a line break inside it. Otherwise it allows line breaks around it, except in some numeric contexts.
The CLDR project calls this character “contains as member” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: as, contains, element, member.
