U+A37F "ꍿ" Yi Syllable Rruo is part of the Yi script, specifically the Liangshan Standard Yi syllabary used to write the Nuosu language spoken by the Yi people in southwestern China. This character represents the sound "rruo," which is a retroflex nasal-initial syllable pronounced with a mid tone in the standard dialect. It belongs to a block of Unicode encoded at U+A000 to U+A4CF, which was added to support the preservation and digital communication of Yi language materials, such as traditional songs, historical records, and modern texts.
