Thanks for the pointer, I wasn't aware of that project.
Anyway I am quite happy with the mentioned regex library and can live
with trading this full compliance for some non-unicode goodies (like
unbounded lookbehinds etc.), but I see, it's beyond the point here.
Not that my opinion matters, but I can't think of, say, "union,
intersection and set-difference of Unicode sets" as a basic feature or
consider it a part of "a minimal level for useful Unicode support."
