I'm not sure what the state of nslookup is these days with respect to
support for idn. One would think it should accept umlauts and translate to
punycode. I can see how a lack of idn support can cause even programmers

Thats how it should work. Its more of a cosmetic user thing and if browsers
did that much user confusion would be reduced if they could see the idn
domain instead of so an xn--* domain. Now there could very well be a browser
that does this. I don't know - the last time I tested this was back when
Ubuntu 7.?? was released. Don't remember the exact date and the only browser
I tested it on was Firefox.
Have you tried other browsers? And what browser(s) have you tested this on.
You have hit on a very important point here.
