Andrew, I only meant that the registry be more restrictive with issues such as identifying common vs historic native digits, not the more general problem of visually similar characters. If the list of common vs historic digits is well-defined and easily known then this is a non-issue, since it can be universally applied. If not, then we shouldn't prescribe that clients guess at the list. Asmus message indicated it wasn't well prescribed and varied regionally, unless I misunderstood his meaning. tex -----Original Message----- From: ua-discuss-bounces@icann.org [mailto:ua-discuss-bounces@icann.org] On Behalf Of Andrew Sullivan Sent: Friday, September 29, 2017 5:32 PM To: ua-discuss@icann.org Subject: Re: [UA-discuss] UASG010 - Quick Guide to Linkification On Fri, Sep 29, 2017 at 05:28:50PM -0700, Tex Texin wrote:
The domain registry (and perhaps servers) should be more restrictive to not allow domains that could represent spoofing.
The problem is that that is not a well-specified criterion. Do you want registration rules about l vs 1? A -- Andrew Sullivan ajs@anvilwalrusden.com
