from Wikipedia, the free encyclopedia

The letter Ø (lower case ø ) occurs in Danish , Norwegian , Faroese , South Sami , Old Swedish and Old Icelandic . The letter and its pronunciation correspond to the " Ö " in German , Swedish and Icelandic . Ø can be transcribed as "Ö" (eg into German or Swedish), " Œ " (eg into French ) or " O E " (eg into English ) .

Alphabetical sorting

In Danish, Norwegian and Faroese, the "Ø" is placed at the end of the alphabet after the "Z" (in Faroese "Ý"), with the Danish and Norwegian alphabet ending in "Æ", "Ø", "Å". The Faroese alphabet ends in "Æ", "Ø".

Like the Icelandic and Swedish "Ö", the "Ø" is not sorted into "O". This has to do with the fact that the "international Ö" (the German Ö) is perceived as a ligature " Œ " from "O" and "E" and is sorted accordingly, while the "Nordic Ø" is an independent letter.

Use as a replacement character

For technical reasons, the large Ø is sometimes used instead of the similar looking symbols for diameter or average (arithmetic mean) and empty quantity (∅) . However, this is typographically incorrect and should generally be avoided. In addition to writing out the intended description, a possible solution is to use the respective symbol provided .

Representation on computer systems

In ASCII - character set , the characters are not included, which is why many older computer systems they could not represent. However, the ASCII extension ISO 8859-1 (also known as "Latin-1") in 1986 contained the two Scandinavian letters "Ø" and "ø". Almost all modern computers use the Unicode standard introduced in 1991 and can thus process and display the characters without any problems.
