U+00D6 "Ö" Latin Capital Letter O with Diaeresis Unicode Character

U+00D6 "Ö" Latin Capital Letter O with Diaeresis is a grapheme used in several languages, most prominently in German, Swedish, Finnish, and Hungarian, where it represents a distinct vowel sound formed by rounding the lips while pronouncing an "e" sound, similar to the "ur" in "fur" in some English dialects. In German, it is considered a separate letter and often sorted alongside "O" in dictionaries, while in Swedish and Finnish it holds its own position in the alphabet after "O". Historically, the diaeresis (two dots) evolved from a small "e" written above the "O" to indicate umlaut, marking a fronting of the vowel. This character is also used in romanization systems for languages like Turkish and Azerbaijani, and it appears in loanwords in English, such as in the name "Zoë" or the rock band "Blue Öyster Cult."
