Yep. One aspect was already mentioned "NUL" characters. The obvious counter
measurement was also mentionen "base64". But this reduces the possible input
variation. It might be possible to mount an attack on it.

The general rule is: If you fear, that the default algorithm is not safe,
change it! You can't incease security by chaining algorithms.
