Ezh
Ezh (capital Ʒ, lowercase ʒ) is a character in the IPA: . Also called the Tailed Z, it is a voiced postalveolar fricative. (SAMPA: [Z])
Ezh is used for the 's' sound in words like vision: /ˈvɪʒən/ (SAMPA: ["vIZ@n])
In Unicode 1.0 the character was mistakenly unified with the quite different character Yogh, which was not added to Unicode until Unicode 3.0. Yogh was used in the old English alphabet. Ezh is used in some othographies of the Sami languages, both by itself, and with a hacek.
Ezh must not be confused with Yogh (Ȝ, ȝ): Ezh resembles a 'Z' with a tail, while Yogh resembles a Arabic numeral 3 which is placed partially below the baseline. To differentiate between ezh and yogh further, the Oxford University Press and the Early English Text Society extend the uppermost tip of the 'yogh' 3 into a little curvature upward.
Ezh is similar in appearance to the 'z' glyph as was used in the German Fraktur script, but it is a different character.
