U+0390 "ΐ" Greek Small Letter Iota with Dialytika and Tonos Unicode Character

U+0390 "ΐ" Greek Small Letter Iota with Dialytika and Tonos is a combination character used in modern Greek writing to represent the letter iota (ι) when it requires both a diaeresis (the two dots, or dialytika) and an acute accent (tonos) simultaneously. This specific glyph appears in words where the iota is pronounced separately from a preceding vowel, often to indicate a stressed, distinct syllable, and it is a precomposed form that ensures correct rendering across digital text systems. It belongs to the Greek and Coptic block of Unicode and is distinct from sequences that attempt to stack the dialytika and tonos separately, making it an essential character for accurate Greek orthography and typography.
