Internationalized Domain Name (IDN) enables the use of non-English native language names as host and domain names. To use non-English host and domain names, application developers must convert names into ASCII Compatible Encoding (ACE) names in their applications as specified in the RFC 3490. System administrators and end users must use ACE names in the existing system files and applications where the networking or system administration applications do not support non-English IDNs.
