Hi list,
I'm working on ticket: https://fedorahosted.org/freeipa/ticket/3169
UTF-8 DNS names will be converted to punycode ASCII string and stored
But there is a question, how to show DNS names to user (in UI or
dnsrecord-show/find):
* show them in punycode
* convert them to UTF-8 and show
* both ways
* add options to show them in UTF-8
I'll be thankful for your opinion.
We have a rule that all strings use UCS and that UCS be interchanged by
encoding UCS text in UTF-8. Therefore it seems to me the only time
punycode should ever exist is when it's necessary to encode/decode
punycode for dns operations. Since punycode is a standard Python codec
this should be trivial, you just need to determine where you do the
encode/decode (perhaps also validating user input can be successfully
encoded).
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.
