Voynichese is a numeric cipher?

Thanks @JoeyB for improving the code ! It should now run without errors and the letters are aligned in order.

@oshfdk, you can try to encrypt your phrase again (I don't fully understand what exactly you've encrypted):

def letter_to_num(letter):

letter = letter.upper()
if letter in ['U', 'V']:
return 21
if 'A' <= letter <= 'Z':
return ord(letter) - ord('A') + 1
return None

def num_to_roman_tokens(num):

tokens = []
roman_rules = [
(22, 'XXII'), (21, 'XXI'), (20, 'XX'), (19, 'XIX'),
(18, 'XVIII'), (17, 'XVII'), (16, 'XVI'), (15, 'XV'),
(14, 'XIV'), (13, 'XIII'), (12, 'XII'), (11, 'XI'),
(10, 'X'), (9, 'IX'), (8, 'VIII'), (7, 'VII'),
(6, 'VI'), (5, 'V'), (4, 'IV'), (3, 'III'),
(2, 'II'), (1, 'I')
]
for val, sym in roman_rules:
while num >= val:
tokens.append(sym)
num -= val
return tokens

def encrypt_word(word):

numbers = [letter_to_num(l) for l in word if letter_to_num(l) is not None]
if not numbers:
return word

numbers.sort(reverse=True)

raw_tokens = []
for num in numbers:
raw_tokens.extend(num_to_roman_tokens(num))

separate_last_i = False
if len(raw_tokens) >= 2 and raw_tokens[-2] == 'III' and raw_tokens[-1] == 'I':
separate_last_i = True
raw_tokens.pop()

i = 0
while i < len(raw_tokens):
token = raw_tokens[i]

if token == 'XV' and i + 1 < len(raw_tokens) and raw_tokens[i+1] == 'XV':
encrypted_tokens.append("che")
i += 2
continue

if token == 'XVI':
