U+10C11 "𐰑" Old Turkic Letter Orkhon Ad Unicode Character

U+10C11 "𐰑" Old Turkic Letter Orkhon Ad is a glyph from the Old Turkic script, specifically the Orkhon alphabet used by early Turkic peoples in Central Asia and Mongolia between the 8th and 10th centuries to inscribe monumental stone stelae, most famously the Orkhon inscriptions. This letter represents the sound /d/ in the Old Turkic language, and its name "ad" likely means "name" in that language, reflecting a common practice where characters were named after the word they initiated. The script is written from right to left, and this particular character is a distinct part of the ancient writing system that helped linguists decipher the historical texts of Turkic khagans, providing crucial insights into early Turkic culture, politics, and language.
