U+046F "ѯ" Cyrillic Small Letter Ksi Unicode Character

U+046F "ѯ" Cyrillic Small Letter Ksi is a historical Cyrillic letter that represents the sound sequence /ks/, derived from the Greek letter Xi (ξ). It was used in the Old Church Slavonic and early Cyrillic alphabets primarily for writing Greek loanwords and numerals, where it also carried the numerical value of 60. This letter was eventually phased out during the orthographic reforms of the 18th century, particularly under Peter the Great’s civil script simplification, and is now considered obsolete in modern Cyrillic alphabets, appearing only in historical or liturgical texts.
