Also known as palochka (Cyrillic)

The palochka () is a letter in the Cyrillic script. The letter is usually caseless. It was introduced in the late 1930s as the Hindu-Arabic digit '1'; on Cyrillic keyboards, it is usually typeset as the Roman numeral ''. Unicode currently supports both caseless/capital palochka at U+04C0 and a rarer lower-case palochka at U+04CF. The palochka marks glottal(ized) and pharyngeal(ized) consonants.
