Ṍ
U+1E4C "Ṍ" Latin Capital Letter O with Tilde and Acute is a precomposed Latin letter used in certain linguistic transliteration systems and scholarly texts to represent a specific phonetic or tonal distinction. It combines a base uppercase O with a tilde (˜) and an acute accent (´), indicating a high-pitched or stressed nasalized vowel sound. This character appears in extended Latin alphabets for languages such as Vietnamese, where it represents the interplay of tone (acute) and nasalization (tilde), though it is rarely encountered in everyday writing. Its inclusion in Unicode ensures consistent digital representation across platforms for academic, historical, or orthographic purposes.
