Are you on OS X?

I am using ruby-2.0.0-p195, and if I install it naïvely I see:

ratdog:tmp mike$ ./try.rb
? \U+FFE5\U+FFBA

0
ratdog:tmp mike$ rbenv version
2.0.0-p195 (set by /Users/mike/.rbenv/version)

If I re-install using the helpful hints at https://github.com/sstephenson/ruby-build/wiki (making sure I have the homebrew openssl and readline installed...)

ratdog:tmp mike$ env RUBY_CONFIGURE_OPTS=--with-openssl-dir=`brew --prefix openssl` CONFIGURE_OPTS=--with-readline-dir=`brew --prefix readline` rbenv install 2.0.0-p195
Downloading ruby-2.0.0-p195.tar.gz...
[...]
ratdog:tmp mike$ ./try.rb ? 出
出
1
ratdog:tmp mike$ rbenv version
2.0.0-p195 (set by /Users/mike/.rbenv/version)

Hope this helps,

Mike
