IDNA 2008 Question Re: "Confusable" Characters in Domain Names

[Vint Cerf]

   If your browser is operating under purely idna2008 rules the lookup
should fail. But some implementations may permit the lookup without verfying
the legality of the characters in the lookup string. V

Dear List Members,

I am a little unclear what impact the IDNA 2008 policy will have on
domain name registrant's who have a domain that does not fall under
the policy's permissible code-points, particularly symbol-based domain
names.

The IDNA 2008 protocol clearly explains what code point are permissible,
but what (in practice) will it mean if someone types in e.g. €.com in their
browser under IDNA 2008?

I do realise that an error message may be displayed, but will IDNA 2008
allow the domain name registrant to satisfy the user's query by forwarding
them on to a different (legal) domain name?

I will hope to hear any replies on this matter.

Regards,

John Daw
