How can I input multibyte characters in rails console (or irb)?

Question

guys. I am developing a Chinese application with rails. Now I want to input some Chinese characters in rails console but cannot do that, either in irb.

Any guys who have the experience to solve this problem? I would appreciate your help!

Answer 1

Based on @Jimmy-Huang's answer, these are the steps I followed on Mac Leopard using rvm and ruby 1.9.2:

rvm package install readline
rvm remove 1.9.2
rvm install 1.9.2 --with-readline-dir=$rvm_path/usr

That resulted in some errors, particularly when trying bundle install:

uninitialized constant Gem::SilentUI

It turned out that's due to an older version of bundler and this gets rid of it:

gem install bundler
