Forgive me if such a function already exists -- I couldn't find it.
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)); // ""
Ah, so this is the way of doing it. Thanks.
It doesn't support negative indexing.
At least dropping off the back is also possible s[2..$-5]:
writeln(s.retro.drop(5).retro.drop(2)); // "rągły"
(or with dropBack, without retro, if available)
I have no idea how to do s[$-4..$-2] though.
