ݙ

ݙ is an additional letter of the Arabic alphabet, not used in Arabic itself but used in Siraiki to represent a voiced retroflex implosive, [ᶑ].

It is derived from dāl (د), with a small ṭāʼ (ط) above to represent retroflexion (as in Urdu), and two dots below to represent implosion (as in Sindhi).
