            Bug ID: 1669
           Summary: Numeric categories missing matches
           Product: PCRE
           Version: 10.10 (PCRE2)
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: bug
          Priority: medium
         Component: Code
          Assignee: p...@hermes.cam.ac.uk
          Reporter: eximbugs.apri...@spamgourmet.com

I’ve noticed that '\p{N}|\p{Nd}|\p{Nl}|\p{No}' doesn’t appear to match some
characters that should be in one of the numeric categories. E. g., ⑤ 
(category
«other number»), Ⅴ (category «letter number»), ₁ (category «other 
number») are
not matched.

I’ve tried this both with PCRE and PCRE2 (built with Unicode property 
support).
In the specs I read that the latest PCRE release is using the Unicode 6.3
tables, so examples above should already have been in there.

I could produce matches for fractions like ½ («other number»), though.
