moin Matteo, moin list,

afaik, the issue you're observing is due to the message box, which uses
t_binbuf internally to (re-)parse messages into pd atoms.  you are
correct that symbols can easily contain spaces (and pretty much anything
else except for ASCII NUL): the problem is getting the funny bytes in &
back out again... anyone else should feel free to correct me on this if
I've got it wrong, of course...
