Failing domain names

I’ve been looking at IDNA domain registrations and using your library in conjunction with the built in python tools.

>>> domain = "xn--53hy7af013i.ws".encode("utf-8")                                                                                     
>>> domain.decode("idna")         
'☕🦊✈.ws'

The IDNA package is a HUGE life saver for me. I monitored approximately over 111,000 IDNA domains being registered, and a small percentage of them failed. I’ve attached the output that I thought you might find useful.

As you can see above, there is an uptick of registrations of emoji domains now. Although it is not part of the specification, it would be very helpful if that was incorporated into this package.

@hynek IDNA2008 disallows symbols and punctionation which € is in the category “Sc” or “Symbols Currency”. If you have to deal with it you could use IDNA 2003:

>>> b"xn--irland-jc1c.com".decode("idna")
'ir€land.com'

It seems like a registry not following standards. 😃

Closing this issue, I’ll keep issue #18 open to track potential changes relating to this. Please add any additional commentary there.
