U+1F3E "Ἶ" Greek Capital Letter Iota with Psili and Perispomeni Unicode Character
U+1F3E "Ἶ" Greek Capital Letter Iota with Psili and Perispomeni is a polytonic Greek letter used in ancient and liturgical Greek to represent the long vowel iota with a combination of two diacritical marks, the smooth breathing mark (psili) indicating the absence of an initial h sound and the circumflex accent (perispomeni) indicating a rising and falling pitch on a long vowel. This character is part of the Greek Extended block, designed to encode classical Greek orthography, and is primarily employed in scholarly texts, editions of ancient manuscripts, and Greek Orthodox religious writings where precise phonological and accentual notation is required. For most modern purposes, this character is not used in standard modern Greek, which employs a simpler monotonic system, but it remains essential for accurately representing historical Greek pronunciation and meter.
