This character is a Other Letter and is mainly used in the Yezidi 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+10E9C forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
Kurdish is written using either of two alphabets: the Latin-based Bedirxan or Hawar alphabet, introduced by Celadet Alรฎ Bedirxan in 1932 and popularized through the Hawar magazine, and the Kurdo-Arabic alphabet. The Kurdistan Region has agreed upon a standard for Central Kurdish, implemented in Unicode for computation purposes.
The Hawar alphabet is primarily used in Syria, Turkey, while the Kurdo-Arabic alphabet is commonly used in Iraq and Iran. The Hawar alphabet is also used to some extent in Iraqi Kurdistan. Two additional alphabets, based on the Armenian and Cyrillic scripts, were once used by Kurds in the Soviet Union, most notably in the Armenian Soviet Socialist Republic and Kurdistansky Uyezd.
