If this patch would be widely used, we'd lose the all the advantages
associated with IDN.
Maybe it's better to attack this problem on the browser side and have a
configuration switch to enable or disable IDN. We could disable it as a
"reasonable default", but those who need it, could enable it.
Upon enabling the option, a warning dialog could pop up that warns the
user about the security problems associated with IDN ("don't enable this
unless you know what you're doing" stuff).
That way the majority of the users would be safe from IDN attacks
(phishing comes to mind) and those who really want IDN would have to
click through a warning dialog telling them why enabling it may not be
such a good idea.
Just my â0.02,
