The first byte in the file is 0xFF which is not a valid UTF8 character, 
likewise the second byte is 0xFE which is also not used in UTF8: so there's 
no way to decode the file and convert to UTF32.

However, if I start reading from the third byte in the file, then the search 
does go through to the end: I can't guarentee that the content was correct 
though !
