How do I register domain names that use local language characters?

all killer.  no filler.

Many world languages use characters that are not found in English. Domain names in these languages are referred to as Internationalized Domain Names or IDNs. You can register IDNs by searching for a domain name in your native language. The availability results are displayed in both the native language and in the IDN format, which begins with xn-- to identify it as an IDN.

When you register an IDN name, you will be prompted for some additional information. As part of the registration process, you are prompted to select the appropriate language code from a drop-down list.

Note: The only TLDs that allow IDN registrations are .COM, .NET, .ORG, .INFO, .BIZ, .CC, .TV, .ME, and .DE.
