# rpm -q perl

# perl -le 'print qq{\xA0} =~ /\h/ ? 1: 0'

This is regression since 5.16.0.

Upstream bug report

commit ee895e3e46998560ad9b18ffcaf5852b1fbc5403
Author: Karl Williamson <public(a)khwilliamson.com&gt;

    PATCH: [perl #114220] /\h/ not equiv to /[\h]/

    \h matches the No-Break space even under /d.  It is the only
    (non-complemented) Posix-like character class that has matches under /d
    in the Latin1 range above ASCII.  A special case is made for it, and \H
    to make sure they have the correct code points.

This will probably go into perl 5.16.1, but it has not yet been merged into
remotes/origin/maint-5.16.
