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. -- Dr Richard Stallman President, Free Software Foundation (https://gnu.org, https://fsf.org) Internet Hall-of-Famer (https://internethalloffame.org)
