Issue #4108 has been updated by Usaku NAKAMURA.

Status changed from Open to Closed
% Done changed from 0 to 100

This issue was solved with changeset r30017.

After applying r30017 and r30018, irb is not working well with
multibyte strings.

On the trunk version,

C:\work>irb
irb(main):001:0> a = "한글"
=> "풉"
irb(main):002:0> a = 1
=> nil
=> nil
=> 1
irb(main):003:0> a = "가나다"
SyntaxError: (irb):3: invalid multibyte char (CP949)
(irb):3: unterminated string meets end of file
from c:/usr/bin/irb.bat:20:in `'

On ruby 1.9.2,

irb(main):001:0> a = "한글"
=> "한글"
irb(main):002:0> a = 1
=> 1
irb(main):003:0> a = "가나다"
=> "가나다"
irb(main):004:0>

=end

I expect that this is fixed at r30019.

BTW, I hear that irb still be in stuck when using readline.
Tarui-san is debugging the problem.

And, the original problem (#4097) is not completely resolved
yet.
The possibility of the buffer overflow and the data disappearance
still remains.
Sorry for the inconvinience.
Please teach us when you find another problem like this.
