As of February 1st 2010 registration of domain names with special characters in them, like for example a letter with an accent, called Internationalized Domain Names (IDNs) .lu will be possible. Acceptable special characters are those commonly used in Luxembourg, German and French languages.
There will be a two months sunrise period between February 1st 2010 and March 31st 2010. During this sunrise period owners of registered .lu names will be able to register the identical names with special characters. After this sunrise period beginning April 1st 2010 IDN registrations will be open for everybody and performed on a "first-come, first-served basis".
