I stand corrected, because I just added those last 2 lines to all language versions. ;-)

Not an issue IMO.

If some part of 1 or 0 is odd, like "1","111","00000"
we need a "round" operation,
"1"-->"1", "111"-->"11","00000"-->"000"

218303231 -> 11  0  1  000000  11  0000  1  0  1  0  11111111
             |   |  |   |      |    |    |  |  |  |    |
             1   0  1  000     1   00    1  0  1  0  1111  -> 83119
