There probably isn't one. A lot of functions are string-only and do not work 
with char[], wchar[], dchar[], wstring, or dstring. That may or may not change 
in the future, but the result is that often the best way to do things is to
just 
use string everywhere and then convert to one of the others when you need to.

A lot of the problem is that to implement string functions for each string type 
tends to up forcing you to actually have at least 3 different implementations
for 
the same function. Range-based functions treat all strings as ranges of dchar, 
so _they_ tend to work with any string type, there are downsides to some 
functions treating a string as a range of dchar, so the functions in std.string 
don't do that, and most functions that specifically want some type of string 
don't do that. It's generally just the functions which deal with generic ranges 
which treat strings as ranges.
