You need IDNA (Internationalized Domain Names for Applications)
Due to restrictions in DNS protocols, the labels are constrained to
contain only LDH (Letter-Digit-Hyphen).
To overcome that, you must convert the zone name using special characters
to ACE encoding.
For example, dcorè.net turns into xn--dcor-8oa.net in ACE encoding.
So you configure in your nameserver a zone for "xn-dcor-8oa.net". Any
IDN-compliant application will encode the name with special characters
into ACE and then, send any query.
If you want to give it a try, visit this
http://www.ñandú.cl or http://www.xn--and-6ma2c.cl you'll get the same!
By the time being, Safari/Mozilla/Firefox/Opera are IDN-compliant
browsers. It was expected that IE7 to support IDN, but I haven't tested it.
