U+10540 "𐕀" Caucasian Albanian Letter Xeyn Unicode Character
U+10540 "𐕀" Caucasian Albanian Letter Xeyn is a glyph from the Caucasian Albanian script, an ancient writing system used between the 5th and 12th centuries CE to record the now-extinct Caucasian Albanian language, primarily in the region of modern-day Azerbaijan and Dagestan. This specific letter represents the sound /x/ or a similar uvular or velar fricative, and it formed part of a 52-character alphabet originally devised by the Armenian monk Mesrop Mashtots. The script was rediscovered through medieval Armenian manuscripts and later confirmed by inscriptions in the 20th century, with U+10540 being added to the Unicode Standard in 2014 as part of the Caucasian Albanian block (U+10530 to U+1056F) to preserve this historical writing system for digital use.
