Sort orders aren't even particularly guaranteed on different releases
of the same platform, let alone totally different platforms. glibc
made major changes to their collation rules not long ago:

At one time we thought that migrating to ICU sorting might bring
a little more stability to this, but I think what we've found so
far is that it's just different :-(
