U+0472 "Ѳ" Cyrillic Capital Letter Fita Unicode Character

U+0472 "Ѳ" Cyrillic Capital Letter Fita is a historical letter used in the early Cyrillic alphabet, primarily in Old Church Slavonic and pre-reform Russian orthography. It was derived from the Greek letter theta (Θ, θ) and represented the voiceless dental fricative sound /θ/, similar to the "th" in the English word "think." In practice, its pronunciation in Slavic languages often merged with the sound of the letter "Ф" (f), leading to confusion in writing. The letter was officially abolished in Russian during the orthographic reform of 1918, being replaced by the letter "Ф" in most cases, though it is still encountered in liturgical texts and historical documentation.
