The Wikipedia has the following information about this codepoint:
Dž (titlecase form; all-capitals form DŽ, lowercase dž) is the seventh letter of the Gaj's Latin alphabet for Serbo-Croatian (Bosnian, Croatian, Montenegrin and Serbian), after D and before Đ. It is pronounced [d͡ʒ]. Dž is a digraph that corresponds to the letter Dzhe (Џ/џ) of the Serbian Cyrillic alphabet. It is also the tenth letter of the Slovak alphabet. Although several other languages (see below) also use the letter combination DŽ, they treat it as a pair of the letters D and Ž, not as a single distinct letter.
Note that when the letter is the initial of a capitalised word (like Džungla or Džemper, or personal names like Džemal or Džamonja), the ž is not uppercase. Only when the whole word is written in uppercase, is the Ž capitalised.
The capitalized version of this letter ('DŽ'), as a single character in Unicode, is also the largest character amongst every Latin character in size (in blocks Basic Latin, Latin Extended-A, Latin Extended-B).
