Polybius Square Bug #91
Description
Describe what you expected to happen
The Polybius Square cipher has a limitation that it does not distinguish between "i" and "j". That is not the bug. The bug is the way in which the program handles this limitation.
During encryption for the Polybius Square, no ciphertext is output when the plaintext is "j".
I believe that a better solution to the "i/j" limitation of the cipher would be to output the same ciphertext for "j" as for "i" during encryption and that the ciphertext for "i/j" should be decrypted as "i" in all cases.
