Unflatten From JSON breaks on NUL characters (LabVIEW 2017+)

[LogMAN]

I recently stumbled upon this issue while debugging an application that didn't handle JSON payload as expected.

As it turns out, Unflatten From JSON breaks on NUL characters, even though Flatten To JSON properly encodes them as ("\u0000").

I have confirmed the behavior in LabVIEW 2017, 2019, and 2020 (all with latest service packs and patches), currently waiting for confirmation by NI.

Workaround: Use JSONtext

I reported that in 2018: CAR 605085.  I don't think they are planning on fixing it.  Must use C strings under the hood.

Thanks, this is very helpful. One more reason to replace the built-in functions with your library.
