--- Comment #2 from Philip Hazel <p...@hermes.cam.ac.uk> ---
A closer look at Perl shows that it warns for [[:ascii:]-X] but not if the
hyphen is the last character in the class, as in your example. I had not
noticed this subtlety. I have just committed a patch (in time to make it into
10.30) that allows a hyphen as the last character in the class, whatever
precedes it. This makes "put a hyphen as the first or last character" always
true.
While doing this I discovered a different bug: PCRE2 was not giving an error
for [\d-X] whereas Perl gives a warning. I have changed this so that \d and
[:digit:] behaviour is the same.
Thank you for raising this issue.
