U+02A4 Latin Small Letter Dezh Digraph

The Wikipedia has the following information about this codepoint:

The voiced palato-alveolar sibilant affricate, voiced post-alveolar affricate or voiced domed postalveolar sibilant affricate is a type of consonantal sound, used in some spoken languages. The sound is transcribed in the International Phonetic Alphabet with ⟨d͡ʒ⟩ (formerly the ligature ⟨ʤ⟩), or in some broad transcriptions ⟨ɟ⟩, and the equivalent X-SAMPA representation is dZ. This affricate has a dedicated symbol U+02A4 ʤ LATIN SMALL LETTER DEZH DIGRAPH, which has been retired by the International Phonetic Association but is still used. Alternatives commonly used in linguistic works, particularly in older or American literature, are ⟨ǰ⟩, ⟨ǧ⟩, ⟨ǯ⟩, and ⟨dž⟩. It is familiar to English speakers as the pronunciation of ⟨j⟩ in jump.
