IDNs are most commonly used in many European countries.
In german, the letters ä, ö, ü, and ß are called Umlauts. These Umlauts are widely used in German, Austria and some part of Switzerland where Germanic keyboard is in use.
When the use of an umlaut is not permitted, either because all the letters are capitalised, or because the writer does not have access to a font incorporating umlauts, the letter "e" is used immediately after the umlauted letter. An example would be München: when the umlaut is unavailable it is spelled Muenchen.
