U+222A Union

U+222A was added in Unicode version 1.1 in 1993. It belongs to the block U+2200 para U+22FF Mathematical Operators in the U+0000 para U+FFFF Basic Multilingual Plane.

This character is a Puntuación matemática and is commonly used, that is, in no specific script. El carácter es también conocido como cup.

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 not mirrored. If its East Asian Width is “narrow”, U+222A 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 glyph can be confused with one other glyph.

The CLDR project calls this character “unión” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: colección, conjunto.

El Wikipedia tiene la siguiente información acerca de este punto de código:

In set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection. It is one of the fundamental operations through which sets can be combined and related to each other. A nullary union refers to a union of zero (0) sets and it is by definition equal to the empty set.
