Readline differences from 1.9.2 to 1.9.3?

Ruby

Here’s my test program:

#!/usr/bin/env ruby

require ‘readline’

ans = Readline.readline("? ", false)
puts ans
puts ans. length

and here’s my test session with Ruby 1.9.2 and Ruby 1.9.3

11:00 cards:>rvm use 1.9.2
Using /Users/bryanloc/.rvm/gems/ruby-1.9.2-p320
11:00 cards:>./tester.rb
? 出

11:00 cards:>rvm use 1.9.3
Using /Users/bryanloc/.rvm/gems/ruby-1.9.3-p392
11:01 cards:>./tester.rb
? \U+FFE5\U+FFBA

OK, am I doing something wrong, or do I need to do something special to
get Chinese characters?
A simple call of gets(), i.e. not using readline, works fine, and
returns the Chinese character.

Thanks in advance,

Bryan

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
Home · rbenv/ruby-build Wiki · GitHub (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

Hope this helps,

Mike
