U+220C DOES NOT CONTAIN AS MEMBER: ∌ – Unicode

U+220C 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 Contains As Member, 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 Not An Element Of. The word that U+220C forms with similar adjacent characters prevents a line break inside it.

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. For example, given a set called A containing the first four positive integers ( $A = {1, 2, 3, 4}$ ), one could say that "3 is an element of A", expressed notationally as $3 \in A$ .
