According to the RFC, that should be escaped:
 All Unicode characters may be placed within the
 quotation marks except for the characters that must be escaped:
 quotation mark, reverse solidus, and the control characters (U+0000
 through U+001F).
And indeed:
>>> json.loads('"\u0000"')
Traceback (most recent call last):
