I.e. if we assume $x holds an Unicode codepoint value (i.e., an integer) do we have a good built-in way to generate the corresponding utf8 sequence? If not, then I think this class may be a good place to put such a function in.

You mean something along the lines of JavaScript’s 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 “ABC”. If we add that, we should also have an analogue of JavaScript’s String.charCodeAt/String.codePointAt to do the operation in reverse.

We already have the single-byte versions: chr() and ord(). It's been on my to do list for a while to rewrite the manual pages for those, which currently have a whole lot of misleading references to ASCII.
