It seems like the best way to go is to use dchar for strings (i.e. not have
the struct as a template) as I need real characters for intersection purposes.
When it comes to lookup, any input will need converting to dchars (I expect
this can be done on the fly).

In C++ you would use iterators to do this kind of input conversion. I don't
know what the technique is in D.

import std.conv;

void charDoThing(charT)(charT[] stuff) {
    dchar[] sameStuff = to!(dchar[])(stuff);

like

import std.array;

string s;
dchar first = s.front;
dchar last = s.back;

or

import std.utf

string s;
int old_offset;
int offset = stride(s, old_offset)

dchar d = decode(s, old_offset + offset);

import std.range;

auto s = "Hello world!";
s.front; // Returns dchars

Is this what you want?
