Pi took me a couple of goes, and when I drew a somewhat narrow ampersand, it gave me a few erroneous results. Both were successful, and put the desired character at the top of the list. All the others worked first time. It would be excellent if it could be made to learn, with users being able to say "that's what I meant"
