Unicode characters in Ruby 1.9.3 IRB with RVM

Question

Update: I found almost exact similar question, yet it has slightly different prerequisites and thus doesn't help much.

Given:

• MacOS Lion 10.7.3
• rvm 1.14.2

• ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.3.0]

  Ruby was installed with the following line:

  rvm install 1.9.3 --with-readline-dir=/usr/local/Cellar/readline/6.2.2/

When I fire up irb or rails c and start typing unicode characters, I get:

\U+FFD0\U+FFBF\U+FFD1\U+FFD0\U+FFB8\U+FFD0\U+FFBC\U+FFD0\U+FFB5\U+FFD1

How do I get unicode characters displayed correctly when typing on Ruby/Rails consoles?

P.S. Typing same characters in bash session of Terminal result in proper output.

P.P.S. Just to be clear -- in console I am typing russian characters: are they considered unicode symbols?

Answer 1

RVM has issues with readline installed via homebrew. This gist worked perfectly for me:

$ rvm get latest
$ rvm pkg install readline
$ rvm install 1.9.3 --with-readline-dir=$rvm_path/usr

Instead of install you can use reinstall.

Answer 2

Other solution would be using http://railsinstaller.org it already provides everything compiled for Ruby and Rails, I was working hard to solve all the libraries compilation and provide one package.

Answer 3

only rvm reinstall all --force helped me
