This character is a Other Letter and is mainly used in the Phoenician 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+1090A forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
Kaph (also spelled kaf) is the eleventh letter of the Semitic abjads, including Arabic kΔfΩβ, Aramaic kΔp π‘, Hebrew kΔpΜΧβ, Phoenician kΔp π€, and Syriac kΔpΜ ά.
The Phoenician letter gave rise to the Greek kappa (Ξ), Latin K, and Cyrillic Π.
