Ways to detect that XXXX in JSON \uXXXX does not correspond to a Unicode character?

The simplest approach would be to use ICU in a little program that scans
the file. For example, you could write a little Java program that would
scan the file, and turn any any sequence of (\uXXXX)+ into a String, then
test that string with:
static final UnicodeSet OK = new
// inside the scanning function
boolean isOk = OK.containsAll(slashUString);
It is key that it has to grab the entire sequence of \uXXXX in a row;
otherwise it will get the wrong answer.
