U+0170 "Ű" Latin Capital Letter U with Double Acute Unicode Character

U+0170 "Ű" Latin Capital Letter U with Double Acute is a distinctive glyph used primarily in the Hungarian language, where it represents a long, rounded vowel sound. Visually, it consists of a standard Latin capital U topped with two acute accents stacked vertically, distinguishing it from the single acute found on letters like "Ú." In Hungarian orthography, this character appears in words such as "űr" meaning "space" or "void," and it is the uppercase counterpart to the lowercase "ű" (U+0171). The double acute accent indicates a lengthened version of the front rounded vowel /y/, which is a crucial phonemic contrast in Hungarian, as it differentiates between words like "tűz" (fire) and "túz" (to stuff). Beyond Hungarian, this letter is also adopted by some other languages, like the Chuvash language, to represent similar vowel sounds.
