I have put the [A-Z] feature on the list to think about for PCRE2.
Development is currently frozen because there is currently a release
candidate out for testing. After the next release is out (a couple of

That seems a more involved kind of feature. Again, I've put it on a
list, but I'll wait until Perl 5.22 appears on my box before doing
anything about it.
