U+0477 "ѷ" Cyrillic Small Letter Izhitsa with Double Grave Accent Unicode Character

U+0477 "ѷ" Cyrillic Small Letter Izhitsa with Double Grave Accent is a variant of the Cyrillic letter izhitsa, historically used in Church Slavonic to represent the sound /i/ or /v/, depending on context, and primarily appears in liturgical texts where the double grave accent indicates a specific tone or stress pattern. This character is part of the Cyrillic Extended-B block and is rarely used in modern languages, surviving mainly in scholarly editions of Old Church Slavonic manuscripts or religious publications. Its design combines the base letter izhitsa with a double grave diacritic, distinguishing it from related characters like the izhitsa with kendema or ordinary izhitsa, and it serves as a typographical relic of detailed phonetic notation in ancient Slavic writing.
