U+020D "ȍ" Latin Small Letter O with Double Grave Unicode Character

U+020D "ȍ" Latin Small Letter O with Double Grave is a specialized glyph used primarily in certain Latin-script orthographies and scholarly transliterations, most notably in the standard romanization of Church Slavonic and other Slavic languages where it represents a distinct vowel with double grave accent diacritic. This character appears in the Latin Extended-B block of the Unicode Standard and is derived from the base letter O, modified by two downward-facing grave accents stacked above it to indicate a specific tone or vowel quality, often reflecting a historical or phonological distinction not captured by the single grave accent. Its usage is relatively rare outside linguistic or liturgical contexts, functioning as a precise tool for representing phonetic or orthographic details in academic and religious texts.
