            Bug ID: 31149
           Summary: combining characters (accents) misclassified as punct
                    rather than alpha
           Product: glibc
           Version: 2.37
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: localedata
          Assignee: unassigned at sourceware dot org
          Reporter: vincent-srcware at vinc17 dot net
                CC: libc-locales at sourceware dot org
  Target Milestone: ---

Combining characters such as U+0301 COMBINING ACUTE ACCENT are misclassifie=
d as
punct, while this should be alpha.

With glibc 2.37 under Debian/unstable, I get for this character:

Property alnum : no
Property alpha : no
Property cntrl : no
Property digit : no
Property graph : yes
Property lower : no
Property print : yes
Property punct : yes
Property space : no
Property upper : no
Property xdigit: no

This affects grep: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=3D27681 (w=
here
it is said that the bug is in the GNU libc).

Corresponding Debian bug:
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=3D868654
(which was reported on 2017-07-17 and hasn't got any activity yet).
