U+1FFC "ῼ" Greek Capital Letter Omega with Prosgegrammeni Unicode Character

Unicode Version 17.0

U+1FFC "ῼ" Greek Capital Letter Omega with Prosgegrammeni is a historic Greek letter used in ancient and polytonic Greek orthography, representing the long omega vowel (Ω) combined with a subscript iota, known as prosgegrammeni, which is written as a small iota attached to the lower right of the capital letter. This form appears in ancient texts, particularly when the omega is the final letter of a word and the iota was originally pronounced but later became silent, serving as a diacritical marker for grammatical or declensional purposes. In modern usage, it is often converted to a simple omega when rendering in monotonic Greek, though it remains important for scholarly editions and reproductions of classical manuscripts.
