Luxembourg's domain will include IDN names.

The Luxembourg domain .LU will feature characters from national domain names. Luxembourg has three official languages: Luxembourgish, German, and English. Residents of the country will be able to register domain names using characters from these languages.

Until March 31, 2010, the .LU domain will undergo a priority registration period, allowing owners of standard domain names to register their internationalized equivalents. Following this, on April 1, 2010, IDN registration will become open to everyone in the .LU domain.
