Note that R can be compiled to use ICU, which provides a well-considered
collation suite. R on Mac OS X uses ICU, as does a Linux build if it is
available -- so I would say that it is RHEL that is out of line here (it

That's not it:

[1] "<0" "1" "2" "<3"
The point is rather that "special characters" are ignored during collation.
Apparently, this comes from /usr/share/i18n/locales/iso14651_t1_common
on Fedora; I wouldn't know how faithful to the ISO standard that is.
