U+1F96 "ᾖ" Greek Small Letter Eta with Psili and Perispomeni and Ypogegrammeni Unicode Character

U+1F96 "ᾖ" Greek Small Letter Eta with Psili and Perispomeni and Ypogegrammeni is a complex, historically rich character used in ancient Greek polytonic orthography, where it represents the long vowel eta combined with three diacritical marks: the psili, indicating a smooth breathing mark pronouncing the vowel without aspiration at the beginning of a syllable; the perispomeni, a circumflex accent denoting a rising and falling pitch contour over a long vowel; and the ypogegrammeni, a small iota subscript written beneath the letter to indicate a long diphthong ending in an iota sound that was no longer pronounced in later Greek. This character appears only in specialized scholarly texts, biblical manuscripts, or linguistic editions of ancient Greek, serving to precisely convey both the phonetic and orthographic nuances of classical or Koine Greek writing.
