U+1F18 "Ἐ" Greek Capital Letter Epsilon with Psili Unicode Character
Unicode Version 17.0
Ἐ
U+1F18 "Ἐ" Greek Capital Letter Epsilon with Psili is a precomposed character used in ancient and polytonic Greek orthography, representing the capital epsilon letter accompanied by a psili, or smooth breathing mark, which indicates that the vowel is pronounced without an initial aspiration. This character appears at the beginning of words that start with an epsilon but lack the rough breathing sound, such as in certain classical texts and scholarly editions. It is encoded in the Unicode Greek Extended block, serving as a distinct glyph for accurate representation of historical Greek writing systems.
