This character is a Other Letter and is mainly used in the Egyptian Hieroglyphs 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+13EFF forms with similar adjacent characters prevents a line break inside it.
The Unikemet database provides additional information about this hieroglyph. It is described there as βA strip of land, with three grains of sand written beneath it, arranged as a triangle, with one grain at the bottom, and a tongue of land (N21) written on either side of the grains of sand.β.
