U+2299 CIRCLED DOT OPERATOR: ⊙ – Unicode

U+2299 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 character is also known as direct product and vector pointing out of page.

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+2299 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 “circled dot operator” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: circled, dot, operator, XNOR.

The Wikipedia has the following information about this codepoint:

The circled dot, circumpunct, or circle with a point at its centre may refer to one or more of these glyphs or articles
