What is Alice and Bob decide to obscure their letters and add random NON-ASCII characters at random places?

Assuming I'm using a statistics based technique, that won't help. Superencipherment might, but then again, thats sort of what 3DES is, right?

If percentage of ASCII characters in all 256 byte space is 40%, Alice and Bob may agree to put in junk characters to make up exactly 60% of the message. This way messages will look like random character data.

Nope, it wouldn't. The statistics would be off. Perry
