I can't actually find documentation to hand to clarify whether it's 12
bits or 12 bytes per character. (My strong suspecion is that it *is* 12
*bytes* - since, after all, a single Unicode code point is 24 bits already.)
The situation is actually worse than it looks. All this lazy evaluation
magic is implemented by storing program state around the place, so an
"unevaluated" string probably takes up more space still...
