U+1E4F "ṏ" Latin Small Letter O with Tilde and Diaeresis Unicode Character
U+1E4F "ṏ" Latin Small Letter O with Tilde and Diaeresis is a composite glyph used primarily in certain linguistic and scholarly transcriptions to represent a specific vowel sound. It combines the base Latin letter O with two diacritical marks: a tilde, which often indicates nasalization, and a diaeresis (two dots above), which can signal a separate pronunciation or a modified quality of the vowel. This character is rarely used in standard modern languages but appears in some phonetic notations, such as for Old English or certain African languages, where it helps distinguish nuanced articulations. Its inclusion in the Unicode standard ensures precise digital representation for researchers, typographers, and linguists needing to encode specialized text accurately.
