The way to do this is to capture the output via a pipe or $(...) or
whatever and then make that output readable by using ${(q)...} or
something such.  There will be examples somewhere.  This does rely on
the shell getting the reverse conversion right, but we test the features
its relying on elsewhere so in theory we shouldn't get errors cancelling
each other out.  (I'm loath to rely on od, and certainly xxd isn't
standard enough.)
