U+1E4E "Ṏ" Latin Capital Letter O with Tilde and Diaeresis Unicode Character

U+1E4E "Ṏ" Latin Capital Letter O with Tilde and Diaeresis is a rarely used composite glyph in the Latin script, designed for phonetic and orthographic transcriptions where a base letter O requires two diacritical marks simultaneously. The tilde above the letter indicates nasalization, while the diaeresis (a pair of dots) below the tilde signals that the vowel should be pronounced separately from a preceding or following vowel, or marks a specific phonetic quality. This character is part of the Latin Extended Additional block and may appear in linguistic texts or transliterations, such as in certain African languages or scholarly works, but it is not a standard letter in any modern writing system. Its usage is extremely limited, and it often relies on specialized fonts or Unicode-compliant software for correct display.
