Thanks for pointing this out. Seem my reply to Kim Barrett.

I don't mind limiting the implementation to 8-bit char platforms, but I
would like to make the specification suitable for other char sizes if
that makes sense.
How do 9-bit char and 32-bit char platforms do disk I/O? Do these
platforms even have disk I/O sub-systems?
