# this file expects to be required from within Homebrew's Ruby environment

# Force UTF-8 encodings.
# * This is not very nice, but we have no control over how Homebrew was
#   invoked, nor with which Ruby interpreter.
# * The correct way would be to invoke Ruby with "ruby -EUTF-8:UTF-8".
# * The Homebrew project prefers to have heterogeneous encodings among
#   its string values.
# * This logic may conceivably cause problems with code that calls back
#   into Homebrew, such as implicit Tapping and Formula dependencies.
# * ARGV may not be the only special variable which needs treatment here.
