U+0342 "͂" Combining Greek Perispomeni Unicode Character

U+0342 "͂" Combining Greek Perispomeni is a diacritical mark used in ancient and polytonic Greek orthography to indicate a rising and falling pitch contour on a vowel, historically denoting a circumflex accent. It is placed above a base character and combines with it to modify pronunciation in contexts like classical texts or liturgical Greek, where it often appears on long vowels to reflect the tonal accent of Ancient Greek. This combining mark is distinct from the similar looking combining tilde and is part of the Unicode block for Greek and Coptic, serving as a vital tool for accurate representation of historical Greek writing.
