I agree that some of the Unicode characters are only slightly different 
and therefore easily confusable.

But then, in the current climate, where phishing is becoming a larger 
problem and identity theft is growing fast, would you say that it is 
safe to use Unicode in *DNS*, one of the most important underpinnings, 
security-wise, of the Internet?

Let's take an analogy. The P.O. Box system. Right now, it uses numbers 
like P.O. Box 3256. What would happen if the Postal Service decided to 
use Unicode, where some of the characters are only slightly different, 
and the postman inadvertently put some important mail into the wrong 
box, one that was registered by an evil person, using a name that was 
only slightly different from the PO box of some company?

Wouldn't that company try to get the Postal Service to use a smaller set 
of symbols (say, digits) rather than this confusing Unicode? Maybe that 
company would even try to sue the Postal Service.
