Hello Mawaki,

It would be useful to give some practical examples here.  Ie strings that you 
would or would not consider confusingly similar across different scripts.

Part of the issue here is that it depends to some degree on how the ASCII 
domain name string is displayed in an application.  At the DNS level it is all 
just ascii.

For example is:

 xn--bruce.example confusingly similar to bruce.example

At the raw ascii level I would probably say no - ie the "xn--" provides 
sufficient differentiation, others may say that they are too similar.

When you then render "xn--bruce" in an application you might get:

??抉.example which looks nothing like bruce.example

Applications may or may not limit the set of scripts that can be used.  So for 
example this email application I am using allows me to mix scripts.

I think the assumption so far is that where two scripts that can appear 
together in the same application at the 1st level would look the same then they 
could fall into the confusingly similar category.

Regards,
Bruce
