Jefsey, you are misreading and potentially misrepresenting my position.

I am NOT saying that that ASCII issues are not part of the IDNABIS  
charter, only that I believe the question of single character ascii  
TLDs or SLDs are not an issue for this working group.

plainly there ARE ASCII issues associated with IDNs because of the  
encoding methods we use.

With regard to single character U-Labels, I am not seeing a protocol- 
based problem but I couched my comments in a way to elicit WG  
reactions, not to declare a WG consensus on the matter.
