My bad; try

ENV.select{|k,v| k=~/^LC/}

Perhaps then:

  env LC_ALL=en_US.UTF-8 ruby foo.rb

Also, looking through source: it seems that ruby doesn't normally call 
setlocale() by itself, but maybe some third-party library which irb is 
invoking is doing this for you. "readline" is a likely candidate. So you 
could try:

  require 'readline'

in your ruby file. Or check $LOADED_FEATURES in irb and try loading the 
same modules in your ruby file.
