About this character

U+0390 (ΐ) is GREEK SMALL LETTER IOTA WITH DIALYTIKA AND TONOS, a lowercase letter in the Greek and Coptic block. It belongs to the Greek script. It was added in Unicode 1.1 (1993).

It has no single-character uppercase form; uppercasing produces the sequence U+0399 Ι + U+0308 ◌̈ + U+0301 ◌́.

It is precomposed. Under NFD it decomposes into U+03B9 ι + U+0308 ◌̈ + U+0301 ◌́, and NFC recombines that sequence into this single codepoint, so both spellings are canonically equivalent and should compare equal after normalization. See the normalization guide.
