Zje

Zje (З́ з́; italics: З́ з́ ) is a letter of the Cyrillic alphabet, formed from З with the addition of an acute accent. It is used in the Montenegrin alphabet. It represents the voiced alveolo-palatal fricative /ʑ/. It corresponds to the Latin Ź.

Origins
One of the first observations of the sound /ʑ/ in Montenegrin, was made by Vuk Karadžić in 1818, in his article "Srpski rječnik istolkovan njemačkim i latinskim riječima" in which he notes that Herzegovians (a cultural region which stretches over Montenegro, thus presumably he also referred to Montenegrins considering he notes words such as iźeo, which are present in Montenegro but not in Herzegovina): "Ercegovci, kašto izgovaraju s pred j kao Poljsko ś, a z kao ź, n. p. sjekira, sjutra, izjeo..." First instance of usage of the accented Cyrillic letter з́ was in 1926. by Danilo Vušović. It came into official use in mid-2009, with the adoption of the Law on the Official Language in Montenegro.

The letter originates from rural areas in Montenegro.

Computing codes
Being a relatively recent letter, not present in any legacy 8-bit Cyrillic encoding, the letter З́ is not represented directly by a precomposed character in Unicode either; it has to be composed as З+Combining Diacritical Marks (U+0301).
