The bit-composition is an issue for XOR which was not my proposition! The modulo solution I suggested based on a 100-year old algorithm makes the issue blissfully irrelevant - it doesn't matter in the least how many bits got flipped if the character is drawn randomly from the printables. Total red herring for me I am afraid, so please drop it.

Update: although I will say that if an enemy suspects your algorithm and has access to the encrypted messages, and the user makes frequent small changes and reapplies it, the enemy can use the fact that half the bits don't change to break the encrypted message by analysis - not even brute force being required. This is not a weakness of the official OTP algorithm.
