I've tested this with DMD 0.85 (or is it 0.86?). Instead of reporting the error message, std.utf prints out:
Error: s


I believe there's an easy fix. In phobos\std\utf.d change line 21 from
	super("s");
to
	super(s);



Here's an example of the error in action:

private import std.utf;

int main(char[][] Args)
{

	dchar[] m_dstring;
	m_dstring = toUTF32(cast(char[]) "\u0000\ubbbf\ufffe\u0a0d\u0d0a");

    return 0;
}

You are, of course, correct. Thanks!
