Cche or Double Che (ê êÂÂ; italics: <span style="font-family: times, 'Times New Roman', serif; font-size: larger">ê êÂÂ</span>) was a letter of the Cyrillic script. It was used in the old Abkhaz alphabets, where it represented the voiceless retroflex affricate . The letter was invented by baron Peter von Uslar. In 1862 he published his linguistic study "ÃÂñàð÷ÃÂúøù ÃÂ÷ÃÂú". The letter was ü-shaped but in 1887 Uslar's study was reprinted by M. Zavadskiy who changed its shape and the result resembled a Cyrillic ç doubled. Later the letter returned to its initial form which, created by linguist Uslar, is now part of the modern Abkhaz alphabet, which is now depicted as ü.
