U+2204 THERE DOES NOT EXIST

U+2204 was added to Unicode in version 1.1 (1993). It belongs to the block Mathematical Operators in the 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 ∃ ̸. It has a Neutral East Asian Width. In bidirectional context it acts as Other Neutral and is mirrored. In text U+2204 behaves as Alphabetic regarding line breaks. It has type Other for sentence and Other for word breaks. The Grapheme Cluster Break is Any.

The Wikipedia has the following information about this codepoint:

In predicate logic, an existential quantification is a type of quantifier, a logical constant which is interpreted as "there exists," "there is at least one," or "for some."

It is usually denoted by the turned E (∃) logical operator symbol, which, when used together with a predicate variable, is called an existential quantifier ("∃x" or "∃(x)"). Existential quantification is distinct from universal quantification ("for all"), which asserts that the property or relation holds for all members of the domain.

Symbols are encoded U+2203 ∃ there exists (HTML ∃ · ∃ · as a mathematical symbol) and U+2204 ∄ there does not exist (HTML ∄).
