Dz is a digraph of the Latin script, consisting of the consonants D and Z. It may represent , , or /z/, depending on the language.
Usage by language
Dz generally represents in Latin alphabets, including Hungarian, Kashubian, Latvian, Lithuanian, Polish, and Slovak. However, in Dene Suline (Chipewyan) and Cantonese Pinyin it represents , and in Vietnamese it is a pronunciation respelling of the letter D to represent /z/. 
Some Esperanto grammars, notably Plena Analiza Gramatiko de Esperanto,
consider dz to be a digraph for the voiced affricate , as in "edzo" "husband". The case for this is "rather weak".  Most Esperantists, including Esperantist linguists (Janton,  Wells  ), reject it.
⟨Dz⟩ is the seventh letter of the
Hungarian alphabet. It is called dzé ( IPA: ) as a letter of the alphabet, where it represents the [d?ze:] voiced alveolar affricate phoneme .
?Dz? and ?dzs? were recognized as individual letters in the 11th edition of
Hungarian orthography (1984). Prior to that, they were analyzed as two-letter combinations ?d?+?z? and ?d?+?zs?.
Like most Hungarian consonants, the sound
/dz/ can be geminated. However, the letter is only doubled in writing (to ⟨ddz⟩) when an assimilated suffix is added to the stem: eddze, lopóddzon.
In several words, it is pronounced
In some other ones, short, e.g.
brindza, dzadzíki, dzéta, Dzerzsinszkij
In several verbs ending in
-dzik (approximately fifty), it can be pronounced either short or long, e.g.
csókolódzik, lopódzik, takaródzik
In some verbs ⟨dz⟩ can be replaced by ⟨z⟩:
csókolózik, lopózik, takarózik, in free variation. In other verbs, there is no variation: birkózik, mérk?zik (only with ⟨z⟩) but leledzik, nyáladzik (only with ⟨dz⟩, pronounced long). In some other verbs, there is a difference in meaning: levelez(ik) "to correspond", but leveledzik "to produce leaves".
Usage of this letter is similar to that of
Polish and Slovak languages: though ⟨dz⟩ is a digraph composed of ⟨d⟩ and ⟨z⟩, it is considered one letter, and even acronyms keep the letter intact.
dz generally represents . However, when followed by i it is palatalized to .
Examples of dz ( dzwon ( · help ) info bell) ( ro dzaj ( · help ) info kind, type)
dz followed by i: ( dziecko ( · help ) info child) ( dziewczyna ( · help ) info girl, girlfriend)
In Slovak, the digraph
dz is the ninth letter of the Slovak alphabet. Example words with this phoneme include:
dzi = between, among hrá dza = dam, dike
The digraph may never be divided by
dzi -> me- dzi hrá dza -> hrá- dza
d and z come from different morphemes, they are treated as separate letters, and must be divided by hyphenation:
dzemok = type of folk dance -> o d- ze-mok na dzvukový = supersonic -> na d- zvu-ko-vý
In both cases
od- ( from) and nad- ( above) are a prefix to the stems zem ( earth) and zvuk ( sound).
Vietnamese Dz is sometimes used in Vietnamese names as a pronunciation respelling of the letter D. Several common Vietnamese given names start with the letter D, including D?ng, D?ng, and Dng. Whereas D is pronounced as some sort of dental or alveolar stop in most Latin alphabets, an unadorned D in the Vietnamese alphabet represents either /z/ (Hanoian) or /j/ (Saigonese), while the letter ? represents a voiced alveolar implosive ( /?/) or, according to Thompson (1959), a preglottalized voiced alveolar stop ( /?d/).  Z is not included in the Vietnamese alphabet as a letter in its own right.
Many Vietnamese cultural figures spell their family names, pen names, or stage names with
Dz instead of D, emphasizing the Hanoian pronunciation. Examples include the songwriter Dzoãn M?n, the poet H? Dz?nh, and the television chef Nguy?n Dzoãn C?m Vân. Other examples include  Bùi Dzinh and Trng ?ình Dzu.
Overseas Vietnamese residing in English-speaking countries also replace D with Dz in their names. A male named D?ng may spell his name Dzung to avoid being called " dung" in social contexts. Examples of this usage include Vietnamese-Americans  Vi?t Dz?ng and Dzung Tran. (Occasionally, D is instead replaced by Y to emphasize the Saigonese pronunciation, as with Yung Krall. )
DZ is represented in Unicode as three separate glyphs within the Latin Extended-B block. It is one of the rare characters that has separate glyphs for each of its uppercase, title case, and lowercase forms.

The single-character versions are designed for compatibility with Yugoslav encodings supporting
Romanization of Macedonian, where this digraph corresponds to the Cyrillic letter ?.
Additional variants of the Dz digraph are also encoded in Unicode.
?, ? and ? (Dz with a caron over z), a digraph used in the Croatian, Bosnian, and Slovak alphabets as a letter in its own right, are encoded at U+01C4, U+01C5 and U+01C6 respectively.
?, a ligature of lowercase dz, historically used to represent the Voiced alveolar affricate in the International Phonetic Alphabet, is encoded at U+02A3.
?, a ligature of lowercase dz with a curl on the z, historically used to represent the Voiced alveolo-palatal affricate in the IPA, is encoded at U+02A5.
?, a ligature of lowercase dz with retroflex hook, used in Sinological and Tibetanist transcription for a voiced retroflex affricate, is encoded at U+AB66.  ? (dezh), a ligature of lowercase d and ezh (a z with a tail), is encoded at U+02A4.
