U+1F64 "ὤ" Greek Small Letter Omega with Psili and Oxia Unicode Character

U+1F64 "ὤ" Greek Small Letter Omega with Psili and Oxia is a combination diacritical letter used in polytonic Greek to represent the long omega vowel with a smooth breathing mark (psili) and an acute accent (oxia) indicating a high pitch. This character is typically employed in classical and liturgical texts to preserve the original pronunciation and grammatical context of ancient Greek, where such diacritics signaled tonal nuance and breath patterns. It appears in editions of ancient literature, religious manuscripts, and linguistic studies, though it is rare in modern Greek writing, which has simplified to monotonic accentuation.
