This character is a Other Symbol and is mainly used in the Braille script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+2801 forms with similar adjacent characters prevents a line break inside it.
