Re: mathvariant vs. plane 1

There was a discussion about this topic a bit in April on the tex@lists.river-valley.com 
  mailing list.
Can't reach the archive.

It would be my naive interpretation that browsers should do the exact  
same thing if either you successfully use the plane-1 character or the  
character with the variant.
Unfortunately, it looks like the specification could not be fully  
detailed about that because plane-1 doesn't have all (fortunately?):
   http://www.w3.org/Math/Group/draft-spec/chapter7.html#chars.BMP-SMP
so it just says it "should" be equivalent.
