You mean something along the lines of JavaScript=E2=80=99s =
String.fromCharCode (or, in ES6, String.fromCodePoint)?

One of the nice things about that function is that it can take multiple =
codes. So I can do String.fromCodePoint(65, 66, 67) to get =E2=80=9CABC=E2=
=80=9D.

If we add that, we should also have an analogue of JavaScript=E2=80=99s =
String.charCodeAt/String.codePointAt to do the operation in reverse.
