U+1E84 "Ẅ" Latin Capital Letter W with Diaeresis Unicode Character
Unicode Version 17.0
Ẅ
U+1E84 "Ẅ" Latin Capital Letter W with Diaeresis is a specialized glyph consisting of a standard capital letter W adorned with two dots, or diaeresis, placed above it to modify pronunciation in certain orthographies. This character is primarily used in linguistic transcription systems, such as in the transliteration of medieval Germanic languages or in the scholarly rendering of specific African and European languages, where the diaeresis indicates that the W should be pronounced separately from adjacent vowels, often marking a syllabic or distinct sound. It is part of the Latin Extended-B block in Unicode, serving as a technical tool for precise textual representation rather than appearing in common modern alphabets.
