The current `String.fromCharCodes` behavior, throwing if `start`
or `end` is larger than the length of the `charCodes` iterable,
is inconsistent with the argument being an `Iterable<int>`,
which the user is not expected to know the length of.
Most other operations that accepts or produces an `Iterable` and
restricts it to a range, will allow the range to exceed the length
of the iterable, acting like `.take(end).skip(start)`, just without
needing to create wrappers that hide the original value.
(`List.setRange` is another exception, and should probably be fixed
by allowing the range to be partially filled, since it's too hard
to change it to require a `List` argument.)
