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);
