U+03AA "Ϊ" Greek Capital Letter Iota with Dialytika Unicode Character

U+03AA "Ϊ" Greek Capital Letter Iota with Dialytika is a glyph used in the Greek script to indicate that the letter iota should be pronounced separately from a preceding vowel rather than forming a diphthong, a diacritical function known as the diaeresis or dialytika. This uppercase character corresponds to the lowercase iota with dialytika (ϊ) and appears in words where the iota must be distinctly articulated, such as in certain loanwords or contexts requiring clarity in pronunciation. It is encoded in the Unicode standard as part of the Greek and Coptic block, ensuring its proper representation in digital text systems that support multilingual typography.
