RE: homograph attacks

Dear Pat,
I have several questions here.

1. where do you maintain an ASCII list of your language tags? Should it not 
be supported on the IANA server and common to all the gTLDs?
2. is there a list of the permitted UNICODEs codes per languages? For 
example I am interested in the French and Ukrainian sets.
3. did you decide them by yourself, or did you gather a group of lingual 
authorities to assist you. This would be very interesting.
4. would there not be a way to register IDN in using their  "xn--" version? 
It would simplify international management by resellers?

Thank you for your assistance.
