I think it's really clear that you don't want to mess with the bytes in any
way without knowing the encoding -- for UTF-16, the code unit is two bytes,
so a "null" is two zero bytes in a row.

So generic "null padded" or "null terminated" is dangerous -- it would have
to be "Null-padded utf-8" or whatever.

That would be nice :-), but I suspect HDF-5 is the same as everything else
-- there are files in the wild where someone jammed the wrong thing into a
text array ....
