U+02DD "˝" Double Acute Accent Unicode Character
U+02DD "˝" Double Acute Accent is a diacritical mark that resembles two acute accents stacked vertically, primarily used in written language to indicate a specific modification to a base letter, most notably in Hungarian where it appears on vowels like 'ő' and 'ű' to denote a longer, more closed sound equivalent to a long ö and ü. It is distinct from the standard acute accent (´) and the umlaut or diaeresis (¨), serving a specific phonetic function in these languages, and can be applied to letters in various writing systems to represent different linguistic features such as tone or vowel quality. As a spacing modifier letter in Unicode, it occupies the combining characters block for diacritics, allowing it to be attached to a preceding character through proper rendering, though it can also appear as a standalone symbol for academic or technical notation.
