U+2209 Not An Element Of

U+2209 was added in Unicode version 1.1 in 1993. It belongs to the block U+2200 to U+22FF Mathematical Operators in the U+0000 to U+FFFF Basic Multilingual Plane.

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 Glyph for U+2208 Element Of, Glyph for U+0338 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 Glyph for U+220C Does Not Contain As Member. The word that U+2209 forms with similar adjacent characters prevents a line break inside it.

The CLDR project calls this character “not an element” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: element.

The Wikipedia has the following information about this codepoint:

In mathematics, an element (or member) of a set is any one of the distinct objects that belong to that set.
