U+022E "Ȯ" Latin Capital Letter O with Dot Above Unicode Character
U+022E "Ȯ" Latin Capital Letter O with Dot Above is a modified version of the standard Latin capital letter O, distinguished by a small dot positioned directly above the letter.

In some contexts, such as Lithuanian or early medieval manuscripts, the dot above a vowel can indicate a particular pronunciation, such as a lengthened or nasalized vowel, or may function as a distinct grapheme in languages like Cheyenne.
