U+1F95 "ᾕ" Greek Small Letter Eta with Dasia and Oxia and Ypogegrammeni is a complex polytonic Greek letter used in ancient and liturgical texts, combining three diacritical marks: a dasia (rough breathing, indicating an initial /h/ sound), an oxia (acute accent, marking high pitch or stress), and a ypogegrammeni (a subscript iota, representing a long diphthong that was once pronounced but later became silent). This character typically appears in classical Greek manuscripts or modern scholarly editions of ancient works, where it helps specify pronunciation and grammatical context, such as in forms of the definite article or certain verb endings.
