Unicode Domain Names

I was watching tv (yes, its christmas time and its cold, so i watch tv) and i noticed that the Portuguese Air Force is recruiting.
The odd thing about this, is that they’re annoucing this url. Depending on your browser, you may or may not be able to check the page out. I tested it on Firefox (mac and linux) and Safari, it worked fine. The sad news is that Internet Explorer seems to fail while trying to resolve this domain name, probably leaving most wanna-be lusitanian air enforcers out of question. I even thought that somehow they typoed the url on the tv ad, so i tried reaching the site with a possible (and cleaner) address: “www.forcaaerea.pt” and it does’nt even exist! Is this a way for the government to recruit more tech-savvy young ones? Or a complete marketing failure ? Or me just being an ass and missing the whole point?
