Source: Browser Default
U+00FF "ÿ" Latin Small Letter Y with Diaeresis is a typographical variant of the letter y that features two dots, known as a diaeresis or umlaut, placed above it. This character is primarily used in the French and Welsh languages, where it indicates that the letter y is pronounced separately from a preceding vowel, as in the French word "crosby" or in Welsh names like "Ffowc" where it appears in certain orthographic contexts. It also occasionally appears in English in loanwords or proper names, such as the surname "Brontë" where the diaeresis marks a distinct syllable. The diaeresis on the y does not change the base sound of the letter but serves a specific diacritical function to guide pronunciation.
