This character is a Other Letter and is mainly used in the Cypriot syllabary 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+10812 forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
The Cypriot or Cypriote syllabary (also Classical Cypriot Syllabary) is a syllabic script used in Iron Age Cyprus, from about the 11th to the 4th centuries BCE, when it was replaced by the Greek alphabet. It has been suggested that the script remained in use as late as the 1st century BC. A pioneer of that change was King Evagoras of Salamis. It is thought to be descended from the Cypro-Minoan syllabary, itself a variant or derivative of Linear A. Most texts using the script are in the Arcadocypriot dialect of Greek, but also one bilingual (Greek and Eteocypriot) inscription was found in Amathus.
