Now, that's a disturbingly cunning idea. Easy, too. And there's plenty
of space at the top of Unicode code point range for these synthetic code
points. I might have to steal that for a non-Lua project; thanks.

Of course, in Lua, since strings are all internalised anyway, you might
as well use string pointers instead of synthetic codepoints; that way
you let the string internaliser do the heavy lifting and avoid needing a
specialised API, and you still get to do comparisons by comparing
pointers...
