U+1E50 "Ṑ" Latin Capital Letter O with Macron and Grave Unicode Character

U+1E50 "Ṑ" Latin Capital Letter O with Macron and Grave is a precomposed character used in certain Latin-based orthographies, particularly for the transliteration of ancient languages such as Latin or Greek, or in specialized linguistic notation where it represents a long O sound (indicated by the macron) combined with a falling or grave accent. This character is formed by combining a standard capital letter O with a macron (a horizontal line above the letter) and a grave accent (a slanted line above and to the left of the macron), and it is encoded as a single code point to ensure correct rendering and text processing in digital systems. While not common in modern everyday languages, it may appear in scholarly texts, dictionaries, or liturgical works that require precise representation of vowel length and tonal stress.
