U+02A5 Latin Small Letter Dz Digraph with Curl

The Wikipedia has the following information about this codepoint:

The voiced alveolo-palatal sibilant affricate is a type of consonantal sound, used in some spoken languages. The symbols in the International Phonetic Alphabet that represent this sound are ⟨d͡ʑ⟩, ⟨d͜ʑ⟩, ⟨ɟ͡ʑ⟩ and ⟨ɟ͜ʑ⟩, and the equivalent X-SAMPA symbols are d_z and J\_z, though transcribing the stop component with ⟨ɟ⟩ (J in X-SAMPA) is rare. The tie bar may be omitted, yielding ⟨dʑ⟩ or ⟨ɟʑ⟩ in the IPA and dz or Jz in X-SAMPA. This affricate has a dedicated symbol U+02A5 ʥ LATIN SMALL LETTER DZ DIGRAPH WITH CURL, which has been retired by the International Phonetic Association but is still used.

Neither [d] nor [ɟ] is a completely narrow transcription of the stop component, which can be narrowly transcribed as [d̠ʲ] (retracted and palatalized [d]), [ɟ̟] or [ɟ˖] (both symbols denote an advanced [ɟ]). The equivalent X-SAMPA symbols are d_-' or d_-_j and J\_+, respectively. There is also a dedicated symbol ⟨ȡ⟩, which is not a part of the IPA. Therefore, narrow transcriptions of the voiced alveolo-palatal sibilant affricate include [d̠ʲʑ], [ɟ̟ʑ], [ɟ˖ʑ] and [ȡʑ].

It is the sibilant equivalent of voiced palatal affricate.
