Interesting article, I've had some similar (though significantly less severe) experiences with having ä and ß in my names, it seems many U. S. companies are just unwilling/incapable of going beyond ASCII.
The government being this sloppy at getting accents right is surprising, I would expect them to value accuracy and a clean paper trail when handling names.
