U+2331 Dimension Origin

U+2331 was added in Unicode version 1.1 in 1993. It belongs to the block U+2300 para U+23FF Miscellaneous Technical in the U+0000 para U+FFFF Basic Multilingual Plane.

This character is a Otro símbolo and is commonly used, that is, in no specific script.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+2331 forms with similar adjacent characters prevents a line break inside it.

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

In mathematics, the origin of a Euclidean space is a special point, usually denoted by the letter O, used as a fixed point of reference for the geometry of the surrounding space.
In physical problems, the choice of origin is often arbitrary, meaning any choice of origin will ultimately give the same answer. This allows one to pick an origin point that makes the mathematics as simple as possible, often by taking advantage of some kind of geometric symmetry.
