Stephane, the issue might be better stated as "can these characters be so readily used to cause confusionas to merit their banishment at protocol level or warned against at "registration time" at all levels in domain name hierarchy?

I believe that the rationale-01 document uses the word "registry" for
them as well:

   Consequently, any DNS zone administration is
   described as a "registry", regardless of that actual administrative
   arrangements or level in the tree. 

[Which seems the right thing to do to me.]

No. Characters never harm. And are never "hostile" despite what
protocol-03 says. What will come next? Terrorist characters?
