U+1F45 "ὅ" Greek Small Letter Omicron with Dasia and Oxia Unicode Character

U+1F45 "ὅ" Greek Small Letter Omicron with Dasia and Oxia is a representation of the Greek letter omicron combined with two diacritical marks: the dasia, which indicates rough breathing and is pronounced as an 'h' sound before the vowel, and the oxia, an acute accent denoting stress or a high pitch in Ancient Greek. This specific character is used in polytonic Greek orthography to transcribe words that require both a rough breathing mark and an acute accent, such as in the word "ὅτι" meaning "that" or "because." It belongs to the Greek Extended block of Unicode and is typically rendered in lowercase script, playing a crucial role in preserving the phonological distinctions of classical and liturgical Greek texts.
