If you want the long answer to that question, see
http://github.com/candlerb/string19/blob/master/string19.rb

The short answer is: (1) Ruby's behaviour when dealing with strings read 
from files is influenced by the contents of environment variables, 
unless you explicitly tell it otherwise; and (2) sudo clears out 
environment variables, unless you explicitly tell it otherwise.

The rules for locale setting are complex, and there are other 
environment variables such as LC_ALL which take precedence over it. See 
'man setlocale'
