This character is a Other Letter and is mainly used in the Syriac 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+072B forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
Shin (also spelled Šin (šīn) or Sheen) is the twenty-first and penultimate letter of the Semitic abjads, including Arabic sīnس and šīnش., Aramaic šīn 𐡔, Hebrew šīnש, Phoenician šīn 𐤔 and Syriac šīn ܫ.
The Phoenician letter gave rise to the Greek Sigma (Σ) (which in turn gave Latin S and the German letter ẞ and Cyrillic С), and the letter Sha in the Glagolitic and Cyrillic scripts (, Ш).
The South Arabian and Ethiopian letter Śawt is also cognate. The letter šīn is the only letter of the Arabic alphabet with three dots with a letter corresponding to a letter in the Northwest Semitic abjad or the Phoenician alphabet.
