But it *is* a single char that I'm wanting to remove (multiple times).
Perhaps you are confusing a char with a byte?
Anyway, the problem is solved from the other end. So long as the
original string has a length that is a multiple of 8 the encoded/decoded
result has no extra chars. Padding the initial string with spaces makes
it easy to then trim() the output.
