Hide UTF-16 assumptions in the API. (#13)

* Avoid the API depending on the underlying data being random-access UTF-16 code units.

In this case, don't return `codeUnits` as a list of integers, but explicitly say `utf16CodeUnits` and return them as an iterable. That can be implemented as efficiently as possible on, say, a UTF-8 byte array.

* Also use .characters in rest of example.
