Yes… see how it was easy to point out that the definition was wrong. It would also have been, if this was code and we were talking about a protocol whose specification was using this notation rather than a new Unicode concept.

Introducing more terminology and jargon is not going to help in this case. Make the definitions as obvious as possible and strive for minimality in the exposed concepts.

I wouldn't say this is advanced knowledge, this is basic knowledge any programmer dealing with Unicode text should have. FWIW this [1] is the absolute minimal knowledge I think programmers should have about Unicode (the last section can be skipped it's specific to a programming language). This corresponds to maybe 3 to 4 A4 pages. If your programmers are not able to grok this small amount of knowledge, hire better ones.
