Name spoofs in non ie browsers (from: Andy)

I actually saw this a couple of days ago but didn’t get round to blogging it but it is now possible to spoof urls in non-ie browsers by using special encoding of characters. A lot of us know that &20 is actually a space, but there are a lot of numbers higher up in the thousands that also look like characters and this is partly to do with the problem. The problem is something called idn.
The link i posted above is reporting on the original website that discovered the problem
Update URL fixed and warning removed. (thanks for the comment Jeff)
