There are a few areas where the term "octet" is used - RFC's around
network protocols are a prime example (so "almost every other document"
was an exaggeration).

I'd be reasonably happy with some other term that doesn't force the 8
bit specification.  But I don't like "char" for storage - the name
"char" implies "character" to me, and "unsigned character" is therefore
meaningless.  "byte" is certainly better, and maybe is the best choice
for C since it fits the definition used in the standard as the smallest
addressable unit of memory.

And then if all non-8-bit char systems were banned from the next C
standards, I'd be even happier :-)
