This would be a matter to take up with the maintainer of your locale
(which you didn't mention, but in any case it's a locale bug).  We
just do what strcoll() tells us.

Note that it's possible this is a configuration error and not an
outright bug.  Check to make sure that the locale you initdb'd
under is actually designed to work with UTF-8 data.
