U+1F49 "Ὁ" Greek Capital Letter Omicron with Dasia Unicode Character

U+1F49 "Ὁ" Greek Capital Letter Omicron with Dasia is a historical Greek letter used in ancient and polytonic Greek orthography, consisting of the capital omicron combined with a dasia, or rough breathing mark, which indicates an initial aspiration or "h" sound before the vowel, making it equivalent to the sound "ho" in English. This character appears primarily in ancient Greek texts, often at the beginning of words, to denote the aspirated pronunciation that distinguishes it from the smooth breathing version without the mark. As part of the Unicode standard, it supports accurate digital representation of classical Greek script, preserving the nuanced phonetic distinctions of ancient writing.
