Thanks, Brian and Simon.
Sorry if this question is a too basic: I'm trying to understand how does
the development cycle or R work. I am running here R 2.8.0 GUI 1.26
(5256) on Mac OS X 10.5.6. The update to 2.8.1 released on 2008/12/22 is
a pending task.
When this option/feature will be included in a dmg available at
http://cran.r-project.org/bin/macosx/?
Thanks you so much for your work,
Ricardo

Some of you will be aware that R ignores locale when collating strings
on Mac OS X: this arises from its inadequate FreeBSD-based wcscoll,
whose man page says
BUGS
The current implementation of wcscoll() only works in single-byte
LC_CTYPE locales, and falls back to using wcscmp() in locales with
extended character sets.
(and conventional Mac OS X locales are not 'single-byte' but UTF-8).
Apple ships a modified version of ICU (IInternational Components for
Unicode) for collation in its ObjC classes, and with Simon's help I
have added code to allow R to use this on Tiger and Leopard. This is
now the default in R-devel, and available in R-patched by configuring
R with --with-ICU.
This originally came up for European Spanish, so in the es_ES locale:
