 I'm well aware why UTF-32 is useful. Earlier, you had
 started out saying 
 that there should only be one string type, the OS-native
 type. Now you're 
 changing your tune and saying that we do need multiple
 types.
 


No. From the very beginning I said "it would also be nice to have some builtin
function for conversion to dchar". That means it would be nice to have function
that converts from tchar (regardless of its width) to UTF-32. The reason was
always clear - you normally don't need UTF-32 chars/strings but for some
character analysis you might need them.

Is this what you want?

	version (utf16)
		alias wchar tchar;
	else
		alias char tchar;

	alias immutable(tchar)[] tstring;

	import std.utf;

	unittest {
		tstring tstr = "hello";
		dstring dstr = toUTF32(tstr);
	}

Function overloading takes care of selecting the right version.
