Sort and LC_COLLATE and utf

[felix]

I have discovered an inconsistency in how perl and sort handle locale.
Here are two commands you can run in a shell ...

    (echo '/'; echo '?') | sort

    (echo '/'; echo '?') | perl -e '@x = <>; print $_ foreach sort @x'

With LANG=en_US.UTF-8, sort says ? comes before /, perl says the
opposite.  Setting LC_COLLATE=C switches the sort behavior.  I have no
idea what else changes or where else perl and sort disagree, or what
other programs do.  For all I know, UTF mandates puncuation sorts
before other things.  I don't know what is proper behavior other than
being different isn't :-)

I have tried this on two systems.  One system is gentoo, sort version
5.94, perl version 5.8.8.  The other system is rPath, sort version
5.2.1, perl version 5.8.7.  I can easily supply further info if you
need it or run other tests.  I am at your service!
