I had been thinking that too.  I do like the direction of focussing the 
requirement on open systems communication though (not to be confused 
with systems built on open software!).  I think the following is pretty 
simple and side-steps issues about what is a network protocol, payload, 
serialization etc.:

8.1.  Character Encoding

    JSON text exchanged between systems that are not part of a closed
    ecosystem MUST be encoded using UTF-8.

    Previous specifications of JSON have not required the use of UTF-8
    when transmitting JSON text.  However, the vast majority of JSON-
    based software implementations have chosen to use the UTF-8 encoding,
    to the extent that it is the only encoding that achieves
    interoperability.

    Implementations MUST NOT add a byte order mark (U+FEFF) to the
    beginning of a networked-transmitted JSON text.  In the interests of
    interoperability, implementations that parse JSON texts MAY ignore
    the presence of a byte order mark rather than treating it as an
    error.
