scope exception do not rise

[Suliman via Digitalmars-d-learn]

void openFile(string fname, string current_folder)
{
        auto file = readText(current_folder ~ fname);
        scope(failure)
        {
                writeln("failure");
        }
//      writeln(file);

}

if file name do not exists, I want to rise scope exception. But 
it's do not rise, and I am getting only standard error like:

std.file.FileException@std\file.d(191): 
D:\code\d\App1\source\app.d1: ╨Э╨╡ ╤Г╨┤╨
░╨╡╤В╤Б╤П ╨╜╨░╨╣╤В╨╕ ╤Г╨║╨░╨╖╨░╨╜╨╜╤Л╨╣ ╤Д╨░╨╣╨╗.

what's wrong? if I use block "success" it's work fine.
