This is a binary representation which has embedded JSON texts represented
in UTF-8.  Since the first character in a JSON text is necessarily in
the ASCII repertoire, it is not possible to parse a UTF-16 or UTF-32
JSON text as UTF-8 and come out with valid JSON.

However, I grant that mentioning UTF-8 only in an ABNF comment is not
really prominent enough.  Proposed wording change:

For:

   In prose: a series of octet strings, each containing any octet other
   than a record separator (RS) (0x1E) [RFC0020], all octet strings
   separated from each other by RS octets.  Each octet string in the
   sequence is to be parsed as a JSON text.

   separated from each other by RS octets.  Each octet string in the
   sequence is to be parsed as a JSON text in UTF-8 encoding.

and add a suitable reference to UTF-8.

Just so.
