I agree, but we need to extend this protection to things other than
program code.

Confusables are dangerous in host names, too.

The same principle could apply: if the host name contains, as well as
the confusables, some non-confusable non-ASCII characters from the
same Unicode page, there is no need to warn about it.

Perhaps there are other cases, too.
