Windows CMD and international chars (åäö

Hi all,

I have been pondering over a problem and I have been trying to find (if
there is any) a solution to it.

I am a Swedish user and I willingly admit that I am a newb with Ruby. I
am trying to create a console based db interface (sqlite) but I am
having problems printing Swedish characters (åäö���). When searching
around and reading up on the problem I seem to run into a dead end
wherever I turn. Solutions concerning this problem when using Rails is
fairly easy to find but so far I have found none when just scripting in
a windows console.

So my question to all you wise Ruby coders out there is this: Is there a
solution to my problem and if so what is it?

Thanks in advance.

You have to set 'Lucida Console' as console font in window properties.
You may change console code page by 'chcp' command:

C:\XP\system32>chcp
Active code page: 1251

C:\XP\system32>chcp 65001
Active code page: 65001 <------- UTF-8

I use this:

# encoding: utf-8

#Kernel::system('chcp 1251>nul')

Encoding.default_external = Encoding.find(Encoding.locale_charmap)
Encoding.default_internal = __ENCODING__

[STDIN, STDOUT, STDERR].each do |io|
io.set_encoding(Encoding.default_external, Encoding.default_internal)
end

puts
"[#{Encoding.locale_charmap}::#{Encoding.default_external}|#{Encoding.default_internal}]"

puts 'Ð?Ñ?евед!'

But I know there is a bug:

C:\XP\system32>ruby -v
C:\users\Administrator\RubymineProjects\TestApp\main.rb
ruby 1.9.1p0 (2009-01-30 revision 21907) [i386-mswin32]

[CP65001::UTF-8|UTF-8]
Ð?Ñ?евед!ед!д!! <------- BUG

It must be 'Ð?Ñ?евед!' not 'Ð?Ñ?евед!ед!д!!'

In windows there are two locales: console (DOS VM) and system (OS) but
Ruby makes no difference.
