std.range have drop and take, which work on code points, not code
units. They also handle over-dropping or over-taking gracefully.
For example:
string s = "okrągły stół";
writeln(s.drop(8).take(3)); // "stó"
writeln(s.drop(8).take(100)); // "stół"
writeln(s.drop(100).take(100)); // ""

It doesn't support negative indexing.
Generally speaking though, the vast majority of user code should
never need to index into a Unicode string.
