If you using Mac OS X (in my case, I’m using Mavericks), during SSH session, you may see this kind of error in your terminal:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "en_US.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
To solve this, edit .bash_profile file in your host/local machine
sudo nano ~/.bash_profile
and add this line:
export LC_CTYPE=en_US.UTF-8 export LC_ALL=en_US.UTF-8
