Hello.
I was trying to run this simple code:

---

import std.stdio;
import std.process;

void main(){
    string a = shell("dir");
}

DMDv2.049/linux works fine, but on windows/DMDv2.051, I've got these errors:

It was on windows with czech locales, standard output from dir should be
something like this:

C:\test>dir
 Svazek v jednotce C nemá žádnou jmenovku.

I think, that shell() is doing some character encoding conversions, but it
fails, because input isn't in UTF/ASCII, but in some obscure windows encoding
(Windows-1252 or something like that).

Is there any way how to fix this problem? Or shell() is lost for everyone who
have system encoding different than UTF/ASCII?

PS: Sorry for my english. Is bad, I know..
