Kha with hook
Kha with hook (Ӽ ӽ; italics: Ӽ ӽ) is a letter of the Cyrillic script. In Unicode, this letter is called "Ha with hook". Its form is derived from the Cyrillic Kha (Х х Х х) by adding a hook to the right leg.
Kha with hook is used in the alphabets of the Itelmen and Nivkh languages, where it represents the voiceless uvular fricative /χ/, like the Scottish ch in loch, but harder. Kha with hook is also used in the Aleut language (Bering dialect). It is the thirty-ninth letter of the modern Aleut alphabet.
The letter Kha with descender (Ҳ ҳ Ҳ ҳ) is sometimes used for this sound instead because of letter font support.
