I think these three are generally accepted.
1) Early Arabic numerals and medieval Latin
abbreviations, as mentioned by D'Imperio and seen in
Capelli;
2) Early Renaissance cipher scripts, as seen in
Trandechino; and
3) Medieval gallows-style letter embellishment, as I
show in a later reply to Petr Kazil.
Other elements, such as Tironian notae, astrological
or alchemical symbols, etc. are much more
controversial.
