"Python 3.0 introduces **additional characters** from outside the
ASCII range" - emphasis mine.

Python currently has - at least, per that documentation - a hybrid
system with ASCII characters defined in the classic way, and non-ASCII
characters defined by their Unicode character classes. I'm talking
about a system that's _purely_ defined by Unicode character classes.
It may turn out that the class list exactly compasses the ASCII
characters listed, though, in which case you'd be right: it's not
hypothetical.

In any case, Pc is included, which I should have checked beforehand.
So that part is, as you say, not hypothetical. Go for it! Use 'em.
