Mac OS X IE 5.2 is the only browser that does this (display the UTF-8 bytes for U+FEFF as a Euro sign). It would indeed be interesting to know why. You can input U+FEFF all by itself in a document and open it with this browser and display a Euro. It's not exactly the same Euro as you get with U+20AC. Weaker, with an extra tail at the top and equal crossbars. Perhaps this indicates a mis-encoded font on the system? But why would no other browser use it? For anyone interested I've put a photo of the two (BOM on top) at: http://homepage.mac.com/thgewecke/bomeuro.jpg
