I had asked earlier for some prose-text statement on the difficulty
of checking NFC.

I can only find

"Detection of un-normalized text is fairly straight-forward, and GCC 10 already produces a warning. Normalizing to NFC is not much more difficult."

which is lacking a bit of depth.

What exactly do I have to do to check for NFC? Check some bits in the code points?
Consult some Unicode tables? Something else?
