In LDAP the values need to be in punycode, so bind-dyndb-ldap can
process them.

IMO all layers above that -- API, CLI, WebUI -- should use Unicode,
except with the `--raw` flag.


Thanks for your opinions.
I will do that as Petr wrote.
After discussing ticket #4020 (ipasam changes for iDNS), please make
sure realmdomains are always written *without* punycode.

realmdomains are just an attribute with UTF8, it is not used by named so
it will not affect DNS driver. However, keeping realmdomains values in
UTF8 will help us by not requiring any modification to ipasam module.
