U+1F10 "ἐ" Greek Small Letter Epsilon with Psili Unicode Character

U+1F10 "ἐ" Greek Small Letter Epsilon with Psili is a polytonic Greek letter that consists of the lowercase epsilon combined with a psili, a diacritical mark indicating a smooth breathing, meaning the vowel is pronounced without an initial 'h' sound in ancient Greek. This character is primarily used in the scholarly and liturgical representation of Ancient Greek texts, where it often appears at the beginning of words that begin with a vowel and require a smooth breathing mark, such as in the word ἐγώ (I). It is encoded in the Unicode block Greek Extended, which supports the complex orthographic system of polytonic Greek that includes multiple diacritics for accurate historical pronunciation and writing.
