This character is a Other Letter and is mainly used in the Bamum 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+169F9 forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
The Bamum scripts are an evolutionary series of six scripts created for the Bamum language by Ibrahim Njoya, King of Bamum (now western Cameroon). They are notable for evolving from a pictographic system to a semi-syllabary in the space of fourteen years, from 1896 to 1910. Bamum type was cast in 1918, but the script fell into disuse around 1931. A project began around 2007 to revive the Bamum script.
The Bamum script is also used to write the ShΓΌmom language, also invented by Njoya.
