This character is a Other Letter and is mainly used in the Arabic script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written as Arabic letter from right to left. When changing direction it is not mirrored. The word that U+066F forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.
The Wikipedia has the following information about this codepoint:
Qoph is the nineteenth letter of the Semitic abjads, including Arabic qāfق, Aramaic qop 𐡒, Hebrew qūp̄ק, Phoenician qōp 𐤒, and Syriac qōp̄ ܩ.
Its original sound value was a West Semitic emphatic stop, presumably [kʼ]. In Hebrew numerals, it has the numerical value of 100.
