U+1FE7 "ῧ" Greek Small Letter Upsilon with Dialytika and Perispomeni Unicode Character

U+1FE7 "ῧ" Greek Small Letter Upsilon with Dialytika and Perispomeni is a precomposed character used in polytonic Greek orthography, representing the letter upsilon (υ) with both a diaeresis (dialytika), which indicates that the vowel is pronounced separately from a preceding vowel, and a perispomeni, a circumflex accent that marks a rising and falling pitch on long vowels. This specific combination typically appears in ancient or liturgical Greek texts to ensure precise pronunciation, such as in the word "ῧψος" (height), where the diacritics clarify that the upsilon is both a distinct syllable and carries a specific tonal contour.
