Good point --- in fact, the encoding itself might be different between
the backend and frontend. That seems to imply that "truncate to
NAMEDATALEN bytes" could yield different results in the frontend than
what the backend would get.

Given the above point about encoding differences, I think we *must*
do the truncation in the backend ...
