translating the net or Phishing new waters

The BBC had this article about the new allowance for none latin characters in Urls. This means that bbc.co.uk can be registered but so can  \u0622 \u0622 \u0623 .co.uk which is unicode for the arabic letters of bbc! Now my wonder on this subject is I wonder how the phishing attack will use this and the browser will differentiate the two from a English language browser when they ar actually two different entity's on the net.

Just something to think about for a new Phishing attacks anyone?
