That's so much code than next code.

///////////////////////////////////////////////
extern(C) int setlocale(int,char*);

static this()
{
	import core.stdc.wchar_;
	import core.stdc.stdio;
	fwide(core.stdc.stdio.stdout,1);
	setlocale(0,cast(char*)"china");
}

But After D2.078.1,it's not work.
Why?
Thank you.
