This character is a Other Letter and is mainly used in the Lydian script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written from right to left. When changing direction it is not mirrored. The word that U+10920 forms with similar adjacent characters prevents a line break inside it.
El Wikipedia tiene la siguiente información acerca de este punto de código:
Lydian script was used to write the Lydian language. Like other scripts of Anatolia in the Iron Age, the Lydian alphabet is based on the Phoenician alphabet. It is related to the East Greek alphabet, but it has unique features.
The first modern codification of the Lydian alphabet was made by Roberto Gusmani in 1964, in a combined lexicon, grammar, and text collection.
Early Lydian texts were written either from left to right or from right to left. Later texts all run from right to left. One surviving text is in the bi-directional boustrophedon manner. Spaces separate words except in one text that uses dots instead. Lydian uniquely features a quotation mark in the shape of a triangle.
