It was a problem of Firefox DNS cache.
Althougth it makes little sense for me thinking about it now, it was the correct solution to try and reset firefox dns.
Once DNS (that were set to last 30 days, or 2592000") were flushed, Firefox correctly redirected me to the right website instead of the default.
There wasn't anything helpful in my access_logs or error_logs sadly, and wildcard weren't much helpful as well, but thanks anyway for the help itpp2012.
Punycode (xn--nicolzanetti-rhb) were the answere, once the DNS were flushed at least.
Therefore my correct configuration is:
server_name
www.xn--nicolzanetti-rhb.com xn--nicolzanetti-rhb.com
www.nicolòzanetti.com nicolòzanetti.com
www.nicolozanetti.com nicolozanetti.com;
If works perfectly in IE, FF and Chrome, in Opera the url doesn't get translated but it works, I see xn--nicolzanetti-rhb.com in the url bar instead of nicolòzanetti.com, but that's not a big concern.
I'll have now to find a way to configure the email as well, since as with opera I see the punycode url, but that's on me.
I am writing this last comment in hope that it will be useful to somebody else someday.
