U+10404 "π" Deseret Capital Letter Long O Unicode Character
Unicode Version 17.0
π
U+10404 "π" Deseret Capital Letter Long O is a typographic symbol from the Deseret alphabet, a phonetic script developed in the midβ19th century by the Church of Jesus Christ of Latterβday Saints under Brigham Young to simplify English spelling for Mormon pioneers. This specific character represents the long "O" sound, as in the English word "go" or "bone," and appears in the uppercase form within the Deseret block of Unicode, which was added to support digital preservation of historical texts. The script saw limited use before falling out of favor, but modern Unicode encoding allows researchers and linguists to access and study this unique writing system in digital environments.
