U+1FC7 "ῇ" Greek Small Letter Eta with Perispomeni and Ypogegrammeni Unicode Character

U+1FC7 "ῇ" Greek Small Letter Eta with Perispomeni and Ypogegrammeni is a precomposed Greek character used in polytonic orthography, combining the vowel eta (η) with a perispomeni (circumflex accent) above and an iota subscript (ypogegrammeni) below. This character represents a long η sound with a falling-rising pitch contour typically found in ancient Greek, where the iota subscript indicates a long diphthong that originated from an earlier ῃ sequence but is no longer pronounced as a separate vowel in later stages of the language. It appears in classical texts, critical editions, and liturgical Greek, primarily in words like τῇ (the feminine dative singular article) or subjunctive verb forms, and is distinct from its decomposed equivalent (U+03B7 η U+0342 combining perispomeni U+0345 combining ypogegrammeni) due to its canonical representation as a single code point.
