This character is a Other Symbol and is commonly used, that is, in no specific script. The character is also known as position of a surface.
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+2313 forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
In geometry, a circular segment or disk segment (symbol: ⌓) is a region of a disk which is "cut off" from the rest of the disk by a straight line. The complete line is known as a secant, and the section inside the disk as a chord.
More formally, a circular segment is a plane region bounded by a circular arc (of less than π radians by convention) and the circular chord connecting its endpoints.
