Unicode Version 17.0
Ὃ
U+1F4B "Ὃ" Greek Capital Letter Omicron with Dasia and Varia is a precomposed polytonic Greek letter primarily used in classical and liturgical texts to represent a specific pronunciation and accentuation of the vowel omicron. The dasia, or rough breathing mark, indicates an initial /h/ sound, while the varia, or grave accent, denotes a lower or falling pitch in ancient Greek orthography. This character is rarely encountered in modern Greek writing, which uses monotonic accents, but it remains essential for scholarly editions of ancient works and religious manuscripts that preserve traditional diacritical conventions.
