That one, and the related ones Ryan mentioned. It’s a fun one. Thanks for digging it up.

The ballot is not affected at all (it wasn’t mentioned in the first two sentences). I believe your first two sentences are correct with respect to current versions of major browsers, but need a small caveat w.r.t. older versions of Firefox. Corey can correct me if I’m wrong, but I was thinking of the Firefox display bugs we stumbled on when he found some spoofing issues with respect to display of xn-- domain components in Firefox. Older versions of Firefox (circa last year?) had some errors in their logic. Like I said, they’re pretty minor, but worth noting. -Tim From: Ryan Sleevi [mailto:[email protected]] Sent: Wednesday, May 23, 2018 11:15 AM To: Tim Hollebeek <[email protected] <mailto:[email protected]> > Cc: CA/Browser Forum Public Discussion List <[email protected] <mailto:[email protected]> >; García Jimeno, Oscar <[email protected] <mailto:[email protected]> > Subject: Re: [cabfpub] Question about CN and SAN encoding On Wed, May 23, 2018 at 11:06 AM, Tim Hollebeek <[email protected] <mailto:[email protected]> > wrote: With regards to the first two sentences, Firefox had some bugs in this area pretty recently, so if you aren’t on the latest version, you might experience issues. They were relatively minor, though. Could you provide a citation for this? I actually carefully watch all of those changes, and am not aware of any recent bugs that would overlap with the ballot or question. It's possible that you're referring to the logic for when A-Label to U-Labels are displayed, but that, if anything, is a very clear argument in favor of Ballot 202, and against U-Labels within CNs.
