i'm trying to read the following codes:

obtaining the following result:
dictionary it: ((21457
dictionary en, fr: (C1457)
and

obtaining the following result:
dictionary it, en: 8E00728l»89
dictionary fr: 8E00728489
Could someone explain me how is the dictionary used on simple codes like these?
I tried also setting the allowed characters string, only to numbers and capital letters, and then i get the first "8" recognised as a "S". How is this algorithm working too?
Thanks
Regards
Marco
