How to enter a Unicode character in a Rails console?

When using the Rails console, entering ä displays \U+FFC3\U+FFA4 . Of course, I can enter Unicode characters outside the rails.

I am using Ruby 2.0.0p247, Rails 4.0.0 on Max OS X 10.7.5.

How can I enter Unicode characters in the Rails console?

Most likely you have a reading problem, try reinstalling 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 /

I had the same problem. After doing many things, including completely reinstalling RVM, I realized that I just needed to define LC variables. To do the same, run these commands on the 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 to save this code in .bash_profile or .bashrc files in the App folder.
