Well, you could ensure that by checking that you haven't reached the
end of the mangling buffer. That will have the added advantage that
when the input is something silly like 32 spaces followed by "utf-8"
it will be still be mangled correctly. The slight extra cost of the
check (could be a single pointer compare) is offset by saving a call
to strncpy().
