I assume you're talking about UTF-EBCDIC from tr16?  I don't see how you
could auto-determine the encoding for that.  How about this:

"""
Without an external mechanism that specifies encoding, when serialized to
an octet stream, JSON text SHALL be encoded in one of the following
Unicode encoding schemes: UTF-8,  UTF-16BE, UTF-16LE, UTF-32BE, and
UTF-32LE.  The default and RECOMMENDED encoding is UTF-8.

Note: the MIME type registered in section 6 does not specify a mechanism
to specify the encoding scheme, so when used in a MIME context, one of the
above encoding schemes MUST be used.


Other Unicode encoding schemes MAY be used, but such octet streams cannot
have their encoding scheme automatically detected and SHOULD NOT be
assumed to interoperate with existing software.
