Weird stream write output

[alkololl]

Hi,

My program does not do what I want it to do.
import std.stdio;
import std.stream;

int main(string[] argv) {
        Stream file = new BufferedFile("D:\\test.txt", FileMode.OutNew);
        char[] patch = [ 0x41, 0x41, 0x41, 0x41, 0x41 ];

        file.write(patch);
        file.close();

        writeln("press enter to exit");
        getchar();
        return 0;
}

gives me this output (the following line is the content of 
test.txt)
|   AAAAA

As you can see there are another 5 characters right before the 
five 'A'.
It seems that D fails with the proper encoding?

Thansk for help
