I tried setting the LANG in ~/.profile and ~/.bash_profile. Both didn’t work.

What worked for me on Mac OS X Sierra is adding the following into my ~/.bash_profile file:

export LANG="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"

Then I reloaded the bash profile with: source ~/.bash_profile

For those who use zsh shell, you must add those lines to your ~/.zshrc

export LANG="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"

Then I reload the bash profile with: source ~/.zshrc
