#8328 — Runtime.getRuntime.exec + Czech windows

I am working on Czech windows and have the problem with the executing
the commands with Runtime.getRuntime().exec(). The special czech
characters are changed during the executing the command.

For example, the file c:\applications\commands\testí\run.bat will not
be executed because the character " í " will be changed on some
character or on ?.

Is there the way to execute the command?

What is the actual Unicode code point (the number) for the í character?

If you wrote a program like this and execed it 

public static void main ( String args[] )
 {
 for ( String arg: args )
   {
   out.println ( arg );
   }
 }

There are two places chars could potentially get scrambled -- coming
in on the command line and going out to the console.   Consoles use
IBMOEM charset which is pretty well guaranteed to screw things up.
see http://mindprod.com/jgloss/encoding.html

A way to tackle this is to write a dummy program that you spawn.  All
it does it dump out the chars from the command line  in hex. That way
you can figure out where the chars are getting scrambled.

It should not be considered an error when the user starts something
already started or stops something already stopped. This applies
to browsers, services, editors... It is inexcusable to 
punish the user by requiring some elaborate sequence to atone,
e.g. open the task editor, find and kill some processes.
