What about the email you just wrote?

I am speaking about the interface required for the processing. The
processing may forward data which is not strictly speaking for the
processing itself. In the given context, low level filesystems need
not know anything about character encodings, as it suffices to use
byte string. One can use character encodings on this low level, and
ot was reoprted one, but not two such systems. There appears to be no
benefit in doing so. So this is a strictly computer-to-computer
interface, even though for debugging pruposes human interfacing
should probably be at hand.

No. It is just the general principles of computer language design.
The human to human interface means that the humans among themaselves
must be able to interpret the computer language. The human to
computer interface means that computer must be able to translate it.
The computer to computer to computer interface means that computer
programs among themselves must be able to translate it. Different
needs in these areas leads to different computer languages.
