U+1FF8 "Ὸ" Greek Capital Letter Omicron with Varia Unicode Character

U+1FF8 "Ὸ" Greek Capital Letter Omicron with Varia is a precomposed character used in polytonic Greek script, representing the capital letter omicron combined with the varia or grave accent, which historically indicates a low or falling pitch in Ancient Greek pronunciation. This character is part of the Greek Extended block in Unicode and is employed in scholarly editions, liturgical texts, and linguistic works that require accurate representation of archaic Greek diacritics. It is typically used in contexts such as the capitalization of words that begin with a grave-accented omicron, though in modern practice the accent may be replaced by a tonos or omitted in monotonic orthography.
