Ezh 
(capital , lowercase ) is a character in the IPA. Also called the tailed z, it represents a voiced postalveolar fricative (SAMPA: [Z]), appearing in e.g. vision: (SAMPA: ["vIZ@n])
As a phonetic symbol, ezh originates with Isaac Pitman's alphabet in 1847, as a z with an added hook. Medieval cursive forms of Latin z, evolving into the blackletter z letter, are very similar in appearance. For purposes of electronic text encoding, however, the latter is considered a glyph variant of z, and not an ezh.
Ezh is used as a letter in some orthographies of the Sami languages, both by itself, and with a hacek (Template:Unicode Template:Unicode). It also appears in the orthography of some African languages, e.g. the Aja language of Benin and the Daghbani language of Ghana, where the uppercase variant looks like a reflected Σ.
Ezh and Yogh
In Unicode 1.0 the character was mistakenly unified with the unrelated character Yogh , which was not correctly added to Unicode until Unicode 3.0. Genetically, ezh is derived from Latin z, while Yogh is derived from Latin g. The characters do look very similar, and do not appear alongside each other in any alphabet. To better differentiate between ezh and yogh, the Oxford University Press and the Early English Text Society extend the uppermost tip of the 'yogh' into a little curvature upward.
