The characters in question are correctly identified as from the "ARIB
STD B62" in the 9.0 code charts. We recognize that "4K" is just a
shorthand term for the standard in question.

And while there may be specific rules for conforming usage in actual
television implementation, the symbols in question were urgently
requested by the Japanese National Body for inclusion in 10646 and the
Unicode Standard, precisely to ensure Unicode *character-based*
interchange and interoperability. See:

 From that document: "Therefore, it is highly expected that the
additional symbols in ARIB STD-B62 are safely interchanged via UCS."

These 19 symbols were accelerated for publication in Unicode 9.0 to
ensure their availability for implementations as of 2016.
