D with hook and tail

 ᶑ (d with hook and tail) is a letter of the Latin alphabet, used in phonetic transcription to represent a voiced retroflex implosive. It is formed from d with the addition of a hooks to mark it as implosive, and a tail to mark it as retroflex. It is thus a fusion of ɗ and ɖ.

ᶑ is not an official part of the International Phonetic Alphabet.

Computer encoding

ᶑ was not added to Unicode until version 4.1 in 2005. As such, few fonts yet support it as of 2006. Those that do include Gentium and Charis SIL.

There is no Unicode encoding for the capital form. However, the Gentium and Charis fonts have  in their private-use areas.
