That's exactly what I have in mind about Java. I can't help wondering why
Sun chose 2byte char instead of 4byte char when it was plainly obvious
that 2byte wouldn't be enough in the very near future. The same can be
said of Mozilla which internally uses BMP-only as far as I know.
Was it due to concerns over things like saving memory/storage, etc?
