I don't think "a little extra string storage" is an accurate
description. It's 4x increase of what you have.

Say you read 100k ascii (or latine-1) text file into buffer,
the buffer needs to be 400k in size (if the string is 32-bit).
If input is 1000k, the buffer will be 4000k. and so on.

I believe that having multiple string types is better.
(If Moore's Law also applies to processor speed, then we can
perhaps ignore a little bit of extra cpu cycles?)

MCL has extended-string which is 16-bit and I like it. I like
it perhaps because I have never cared how it is implemented.
And crucially, Gary doesn't like it (or doesn't seem
enthusiastic about it.)
