Excuse my 'obviously', let me clarify.
The following alphabet is reversable:
for encode: {0 : 'a', 1, 'b'}
for encode/decode: {0: 'a', 1: 'b', 'a':0, 'b':1}
You can have 'a' and 'A' coexist, but the encode will have only one option.
for encode: :{0 : 'a', 1, 'b'}
for encode/decode: {0: 'a', 1: 'b', 'a': 0, 'b': 1, 'A': 0, 'B': 1}
So one could say the encoding alphabet is the canonical representation. The
encoding alphabet is actually alphabet_dict[0],..., alphabet_dict[base - 1].
