A string is defined by:
alias string = immutable(char)[];

It doesn't add anything to that type (unless you import a library like 
std.algorithm, which adds many "methods" thanks to UFCS and generic 
functions)

I believe you are looking for dstring which is defined by:
alias dstring = immutable(dchar)[];

dstring s="weiß";
int i;
foreach(c;s)i++;
assert(i==4);

I don't think so. The range algorithms iterate by dchar though.

 string s="weiß";
 int i;
 foreach(c;s)i++;
 assert(i==5);

Nope.

if you use foreach(dchar c; s) you will get the iteration by 
code-point you are looking for.

Actually I was trying to prevent decoding :) It just occurred to 
me it can be tricky in generic code.
