K with descender
The Latin letter K with descender is a Latin letter.
The letter is very easily confused with the Cyrillic letter ka with descender, which is encoded differently in Unicode, even though it essentially shares the same letter forms.
This Latin letter has been used in China for writing the Uighur language with the former Pinyin-derived “new script” alphabet, borrowing the letter form from the Cyrillic letter, until that alphabet was deprecated and the language was converted back to use the Arabic alphabet.
