The Unicode spec disagrees with you (16.8):

   In UTF-8, the BOM corresponds to the byte sequence <EF16 BB16 BF16>.
   Although there are never any questions of byte order with UTF-8 text,
   this sequence can serve as signature for UTF-8 encoded text where the
   character set is unmarked.

Best wishes,
