This is probably a troll question, but answering anyway: the BOM marker 
U+FEFF is in the correct byte order, in both little-endian and 
big-endian UTF-16. That's how you tell them apart.

The trick is in that the reverse value U+FFFE is not valid Unicode 
character, so there is no possibility of mixup. Neither sequence is also 
valid UTF-8, to avoid mixup with that.
