Could you be more specific about the problems you envision?

If there would be problems in the ruby core functionality it is
perhaps the right time to check for them now by setting LC_ALL from
the environment and waiting for bug reports. This is a development
release after all. That way people could embed ruby 1.9 in
applications that use locale.

I would expect that ruby core classes would behave exactly the same
regardless of locale. A special library might provide get/setlocale
and some locale-dependent formatting functions just like there is
win32api for windows.

Programs called from ruby could give different output in different
locale (eg `date`) but that does not depend on the way ruby sets up
locale for itself, they read the environment variables anyway.

Thanks
