More seriously, you are wasting your precious cycles on already solved and quite simple problems:
https://chromium.googlesource.com/android_tools/+/78ccfd5f7e4880597fd90c61453a3be0e7aee5f0/sdk/sources/android-21/java/lang/Character.java#2058
The slight platform "bias" doesn't actually matter, it is the result that counts.

Personally, I found it more worthwhile looking into the [previously] unsolved problem: canonical serialization of 64-bit doubles.
This was clearly out of my league but I got some excellent help on the way.  The JCS number test suite passes without a glitch for Java, JavaScript, C#, Python and Go:
https://github.com/cyberphone/json-canonicalization/tree/master/testdata#es6-numbers
This scheme also have a clear platform bias.  In fact, the entire JCS specification (modulo sorting) is 100% compatible with ES6's JSON.stringify().

Anyway, if you think that JCS is controversial, that's nothing compared to what it is targeted for:
https://lists.w3.org/Archives/Public/public-payments-wg/2019Sep/0000.html
The 5-level signature depth required made the [previously] mandatory B64U wrapping schemes look really stupid.

thanx,
Anders
