FWIW (and to coin a phrase), I'd consider "www.TRÛMP.com" more of a "pun" than a "confusable". It's evocative of "Trump" but is visually distinct.
But of course, you can't actually register TRÛMP.com at all, because upper case characters are not allowed in U-labels. So you'd have to register trûmp.com, and any sensible Latin variant strategy would require that the undecorated Latin characters would be variants of decorated Latin characters. IDNA2003 doesn't help you here, because it downcases everything as the first part of the ToASCII part. That case mapping is lossy, which is the whole reason we changed it in IDNA2008. (We didn't do IDNA2008 for fun, you know.) A -- Andrew Sullivan ajs@anvilwalrusden.com
