The obvious solution to this is to pre-compile a list of all possible Unicode strings up to the required length, sort them, and create a lookup table using their indices. I wonder for what kind of project this would be useful.

If that works for you for anything but very small strings, I want to buy your computer.

Even for 3-codepoint strings it already wouldn't fit in any computer that exists. And that is not sufficient to encode all 1-glyph strings.
