U+1D3C "ᴼ" Modifier Letter Capital O Unicode Character

U+1D3C "ᴼ" Modifier Letter Capital O is a small, superscript style version of the uppercase letter O, primarily used in phonetic transcription systems such as the Uralic Phonetic Alphabet. It functions as a modifier letter, meaning it adjusts or clarifies the pronunciation of another character rather than standing alone as an independent symbol. In transcription, this character often indicates reduced rounding, a specific vowel quality, or a secondary articulation associated with the sound of a capital O. Its inclusion in Unicode ensures that linguists and scholars can digitally represent specialized phonetic notation accurately.
