Setting Up a UTF-8 Locale
You may need a UTF-8 locale to run some Ruby applications. For example we have found that Ruby Spec needs such a locale.
RedHat-based: Fedora, Oracle Linux, etc #
export LANG=en_US.UTF-8
Debian-based: Ubuntu, etc #
sudo apt-get install -y locales
sudo locale-gen en_US.UTF-8
export LANG=en_US.UTF-8
