Re: Sounds like a good idea
The PDP-8 used 6 bit bytes, and base 64 encoding has hung around for a long time. I confess to having used it in anger before passing guaranteed A-Z/a-z/0-9 data into and out of a link, back in the days when baud rates were low. It's left as an exercise for the reader to work out which byte values, if any, can never occur and so can be used as markers.
