D - converting wide to c

ok i looked thru the string functions an found toCharz() to convert a wide 
string to a null terminated string, but when i tried to use it it told me it 
wasnt appreciated :(  (depreciated lol) so then i of course i tried to write my 
own an failed miserably... would anyone care to give me a hint on how to make 
this work? or is there another function i can use somewhere... thanks

//Convert a wide string to a 'c' string
char[] WideToAscii(wchar[] WideArr) {
	
	int i = 0;
	int Count = 0;
	char[] CharArr;
	
	i.init;
	Count.init;
	
	if ( WideArr.length > 0 )  	{
		
            CharArr.length = (WideArr.length / 2) + 1;
	
             while ( i < WideArr.length )	{
	        CharArr[Count] = (char) WideArr[i];
	        i += 2;
	        Count += 1;
	    }

	}

   CharArr[CharArr.length - 1] = (char)r"0";
   return CharArr;

  }

:) yes i have a long way to go lol

wow i can see a bad habit starting, but how is it possible to have 3 functions 
with the same name? how do i specify which one to use (it just wants to use the 
first one and i get a type mismatch compile error) Do i have to comment out the 
ones that i dont want to use?

sorry if im being a pain

I'm not sure what the problem is.  My blind guess is that you need to 
use a cast:

toUTF8(cast(wchar[]) "your string")
or
toUTF8(cast(wchar[]) str)

(By the way, it does help if you include a snippet of code.  Sometimes, 
the solution is obvious if we see it.)

 It's okay.  They have 3 sets different argument litss: (char[]), 
 (wchar[]), (dchar[]).

 No.  You shouldn't have to comment out anything in phobos.

 Don't worry about it.  We've all starting programming in D fairly 
 recently. :)
