U+1FD1 "ῑ" Greek Small Letter Iota with Macron Unicode Character

U+1FD1 "ῑ" Greek Small Letter Iota with Macron is a precomposed letter representing the Greek iota (ι) combined with a macron, a horizontal line placed above the character to indicate a long vowel sound. This character is used in polytonic Greek orthography, often in classical or scholarly texts, to denote a specific phonemic length in transliteration or teaching contexts, distinguishing it from the short iota. It appears in Unicode’s Greek Extended block and is distinct from a regular iota followed by a combining macron, though it may be displayed similarly in some fonts. Its inclusion aids in precise representation of ancient Greek pronunciation and textual accuracy in digital formats.
