Here is a proof of concept that raises this error:
>>> import json; json.load(open('input.json'))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/wolf/dev/py/2.7/Lib/json/", line 290, in load
  File "/home/wolf/dev/py/2.7/Lib/json/", line 338, in loads
    return _default_decoder.decode(s)
  File "/home/wolf/dev/py/2.7/Lib/json/", line 365, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/home/wolf/dev/py/2.7/Lib/json/", line 381, in raw_decode
    obj, end = self.scan_once(s, idx)
ValueError: Unexpected UTF-8 BOM (decode using utf-8-sig): line 1 column 1 (char 0)

If the idea is OK I will add tests and implement it for the Python scanner too (and possibly tweak the error message if you have better suggestions).
