U+1F4A "Ὂ" Greek Capital Letter Omicron with Psili and Varia Unicode Character

U+1F4A "Ὂ" Greek Capital Letter Omicron with Psili and Varia is a historic polytonic Greek letter used primarily in ancient and liturgical texts, combining the base omicron with two diacritical marks: the psili, which indicates a smooth breathing mark, and the varia, which denotes a grave accent. This character appears only as a capital letter and is part of the Greek Extended block, representing a specific phonetic and tonal detail that is no longer employed in modern Greek writing. Its use is largely confined to scholarly editions, classical manuscripts, and religious scripts where precise accentuation and breathing are preserved.
