My point was that someone who can type it will often have it rejected by a website. I was using a hotel booking site and when I booked a room it asked me for my address so I typed Å... The web page rendered it correctly but when I hit the button to complete the transaction it told me that my address contained an illegal character (or some similar wording). And this site handles bookings for hotels that themselves have names with umlauts, tildes, cedillas, etc.
