I did have the same problem. After done a lot of things, including the complete reinstall of RVM, I'd realized I just need to define the LC variables. To do the same, run these commands on terminal:

LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL="en_US.UTF-8"
export LANG LC_COLLATE LC_CTYPE LC_MESSAGES LC_MONETARY LC_NUMERIC LC_TIME LC_ALL

One good idea is save this code in .bash_profile or .bashrc files in the App folder.

Most likely you've got readline issue, try to re-install Ruby with readline support. https://github.com/wayneeseguin/rvm/issues/1016 or http://blog.rlmflores.me/blog/2012/04/25/adding-utf-8-support-to-rubies-compiled-through-ruby-build/
