First of all, I know nothing.  Of substance, anyway.

The issue is the shifts - they're overhead.  To get more than 32
characters out of 5 bits, Baudot includes a FIGS shift and a LTRS
shift.  As Chen just mentioned, those don't exist in ASCII (or
Varicode).  So the idea we've been batting around is how to transmit
the shortest possible exchange in the most robust way.

Look here http://www.dataip.co.uk/Reference/BaudotTable.php and you'll
see that all the punctuation (and the FIGS) is in the FIGS case. SPACE
is in both, as is CR, LF, and the shifts themselves.
