I have done a lot of work on IDN at DomainSite.com and Name.com, two 
domain registrars that I work for. I wrote a Punycode converter in PHP 
available at http://punycode.bluerider.com/idn/. All registries have 
standardized on Punycode and the old RACE codes are no longer being 
used. If the native representation was used in pdns it would not work on 
the Internet at large because clients (mozilla, opera, various IE plug 
ins, etc) query DNS using the Punycode string. I think any kind of 
unicode -> punycode conversion taking place in pdns would just be dead
