However, the 21st-century view, especially amongst the more educated members of society, is to reserve the term Engineer to describe a university-educated practitioner of ingenuity represented by the Chartered (or Incorporated) Engineer.
I'd challenge that bit - an awful lot of people (me included) who haver a career in engineering never bothered to get Chartered status because it was of no benefit to what we were doing. If you're doing certain types of job then it is useful, but for the most part the simplistic view is that it's paying out money to be able to have CEng after your name. Ironically, the people who benefit most are the ones who did not get a degree and did the hard slog up the route requiring 15 years' experience because to them, it's a piece of paper showing they're at least equal to the ones with degrees and that does have value with employers.
