Description

Having a "special" character on a line (such as £ ¤ §) causes Jirb to terminate immediately with exit code 0 (checked from bash with echo $?)

Having the same character on a single line i a script file run with "jruby", instead gives a syntax error:
:1: /home/larsw/tmp/jirbbug.rb:1: Invalid char `\243' ('£') in expression (SyntaxError)

For what it's worth, this also happens with ruby 1.9.x. 1.8.x irb doesn't accept these characters as input.

Correction. This is OK if you compile MRI with GNU readline support.

I believe this is an issue with jline.

Still appears to be a problem with jline 1.0-snapshot, but 1.9 mode at least presents an error:

~/projects/jruby ➔ jirb
>> £

~/projects/jruby ➔ jruby --1.9 -S jirb
>> £
NameError: undefined local variable or method `?' for main:Object
	from (irb):1:in `evaluate'
	from org/jruby/RubyKernel.java:1087:in `eval'
	from org/jruby/RubyKernel.java:1412:in `loop'
	from org/jruby/RubyKernel.java:1199:in `catch'
	from org/jruby/RubyKernel.java:1199:in `catch'
	from /Users/headius/projects/jruby/bin/jirb:13:in `(root)'
>> quit

My guess would be that encodings are getting mucked up passing through jline, and only the 1.9 parser is able to cope with it. Note that the resulting character is "?", the default replacement character for anything that can't be decoded into UTF-16.

Looking at this on JRuby 1.7...

The issue remains, and I've confirmed that it fails with or without readline loaded. So this is some console or IRB-specific encoding problem, not related to jline.

Updating version info.
