Instead of trying to come up with an updated algorithm, the WG recognized that this is not a real-world problem. If 7159bis is supposed to be an Internet Standard, it should focus on the variants that actually interoperate. Re-encoding JSON into UTF-16 (or UTF-32) is not really interoperable with today’s implementations*).

It is not the widely interoperable “JSON” thing, though.)
