Very strange:

1. > ENV.select{|k,v| k=~/^LC/} give en_US.UTF-8 in both irb and ruby. I 
get LC_ALL AND LC_CTYPE.

2. >   env LC_ALL=en_US.UTF-8 ruby foo.rb
still gives 95

3. I copied $LOADED_FEATURES, and then tried out (I hope i have this 
correct):

["enumerator.so", "e2mmap.rb", "irb/init.rb", "irb/workspace.rb", 
"irb/context.rb", "irb/extend-command.rb", "irb/output-method.rb", 
"irb/notifier.rb", "irb/slex.rb", "irb/ruby-token.rb", 
"irb/ruby-lex.rb", "readline.bundle", "irb/input-method.rb", 
"irb/locale.rb", "irb.rb", "irb/completion.rb", 
"irb/ext/save-history.rb", "stringio.bundle", "yaml/error.rb", 
"syck.bundle", "yaml/ypath.rb", "yaml/basenode.rb", "yaml/syck.rb", 
"yaml/tag.rb", "yaml/stream.rb", "yaml/constants.rb", "rational.rb", 
"date/format.rb", "date.rb", "yaml/rubytypes.rb", "yaml/types.rb", 
"yaml.rb"].each do |rr|

    require "#{rr}"
end

I still get 95.
