U+1FD0 "ῐ" Greek Small Letter Iota with Vrachy Unicode Character
Unicode Version 17.0
ῐ
U+1FD0 "ῐ" Greek Small Letter Iota with Vrachy is a precomposed character used in polytonic Greek orthography to represent the letter iota (ι) combined with the breve or vrachy diacritic, which indicates a short vowel sound. This character is part of the Greek Extended block within Unicode and is primarily employed in scholarly texts, such as editions of ancient Greek poetry or linguistic works, to specify that the iota should be pronounced as a short vowel rather than a long one. Its inclusion in the Unicode standard ensures precise representation of ancient Greek accentuation and prosody in digital environments, particularly when distinguishing between vowels that are otherwise identical in modern Greek.
