You're right that this is under-specified,
in both the man page and the info file.
The above is really characters (not bytes).
In fact as a GNU extension it's printable characters.
POSIX does not specify this, but one can confirm like:


$ printf '\xc3 \xc3' | LC_ALL=C wc --word --character --byte
       0       3       3
$ printf '\xc3 \xc3' | LC_ALL=C.utf8 wc --word --character --byte
       0       1       3

The info file was really quite under-specified in this regard.
I'll apply the attached to clarify things.
Marking this as done.

thanks!
