D:\server\ruby\bin>irb
irb(main):001:0> лорлор <---- russian chars

D:\server\ruby\bin> <----- exited

also I can't type any characters with "right alt" using belgium/french keyboard layout ( "AltGr"+2 = @ "AltGr"+3 = # ....)

I always disable readline with this .... no colors, no autocompletion (((((

require File.dirname(FILE) + '/readline/readline'
module Readline
def readline prompt, something
print prompt
return $stdin.gets.strip
end
def self.readline prompt, something
print prompt
return $stdin.gets.strip
end

I don't have any solutions for you, but I think you can reduce your above workaround via:

   @use_readline = IRB.conf[:USE_READLINE]

Setting to false should bypass readline.

It seems the bug of libreadline.
FYI, ruby 1.8.8dev has that the same problem.

the bug is still present when readline is disabled

D:\server\ruby\bin>irb --noreadline

I can confirm that this isn't isolated to windows:

501 % ruby -d -S irb --noreadline

орпррп
502 %

This is in a UTF-8 terminal (on osx) and it doesn't matter if I convert the text above to UTF-8 or not.

Wow:
