U+10377 "𐍷" Combining Old Permic Letter Doi is a combining diacritical mark used in the script known as Old Permic, which was historically employed for writing the Komi language and other Uralic languages. This character is designed to be placed over or adjacent to another letter, modifying its sound, and represents a specific phonetic element from the medieval alphabet created by Saint Stephen of Perm in the 14th century. Codified in Unicode’s Supplementary Multilingual Plane, it serves primarily scholarly and historical documentation purposes, as the script is no longer in common contemporary use.
