Are the usual audio, image, etc. formats truly 8bit clean (i.e. are they
guaranteed not to contain NUL or naked CR or LF)?
Of course they aren't.
Yes, that's what I thought.
If not, then you are
back to the 37+% expansion of base64.
Doesn't follow. A binary-to-8bit encoding has enough characters available that
the overhead can be limited to at most 1-2%.
Sure, but there is no currently recognized/standardized encoding with that
property (except for yEnc, which I don't think is a serious candidate
yet).
