ASCII Character ØLatin capital letter O with slash
Ø (or minuscule: ø) is a letter used in the Danish, Norwegian, Faroese, and Southern Sámi languages. It is mostly used as a representation of mid front rounded vowels, such as [ø] and [œ], except for Southern Sámi where it is used as an [oe] diphthong. In other languages that do not have the letter as part of the regular alphabet, or in limited character sets such as ASCII, "ø" may correctly be replaced with the digraph "oe", although in practice it is often replaced with just an "o", e.g. in email addresses.
