Subject: Windows XP - Path encoding problem prevents script execution

Hello all,

I've installed ruby 1.9.3 on a Windows XP box (french) for work related
purposes, with ruby installer from rubyinstaller.org. (same thing
happened on 1.9.2)

Here is the content of a very simple script
#SCRIPT_START
puts "This should work, press a key to exit"
gets
#SCRIPT_END

The script executes normally if saved to a path such as
"C:\Scripts\Ok\test.rb"

However if saved to a path with an accent for instance
"C:\Scripts\Cliché\test.rb", I get an instant failure if I double click
on the script file.

Going to the command line, if I type:
- C:\Scripts\Ok\test.rb => execution is ok.
- C:\Scripts\Cliché\test.rb => returns following error
"C:/Scripts/ClichÚ/test.rb: No such file or directory -
C:/Scripts/ClichÚ (Errno::ENOENT)"
- ruby C:\Scripts\Cliché\test.rb => execution is ok.

This problem also causes failure if I need to use "require" pointing to
other scripts. For instance if I type inside irb:

require "C:\\Scripts\\Ok\\test.rb" => execution is ok
require "C:\\Scripts\\Cliché\\test.rb" => failure to find file

I have noticed there are many encodings being used all over the place.

For instance in irb :
 - Dir.pwd.encoding.name returns "Windows-1252"
 - "test".encoding.name returns "CP850"

So require "C:\\Scripts\\Cliché\\test.rb".encode("Windows-1252") seems
to solve that problem.

regedit
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\RubyFile\shell\open\command =
"C:\Ruby193\bin\ruby.exe" "%1" %*

So I guess the ruby interpreter is expecting the script name as a string
in another encoding than that which is given by the windows subsystem.

How can I solve this problem ? I would like to keep the double click
functionality, without having to resort to batch file wrappers.

Thanks for your input.
