Kha with hook

Kha with hook is a letter of the Cyrillic script. In Unicode, this letter is called "Ha with hook". Its form is derived from the Cyrillic Kha 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, like the Scottish ch in loch, but harder. Kha with hook is also used in the Aleut language. It is the thirty-ninth letter of the modern Aleut alphabet. In Eastern Khanty's Vakh-Vasyugan dialect it represents the /ɣ/ sound.
The letter Kha with descender is sometimes used for this sound instead because of letter font support.
