Issue when there is 'zéro' before other letters

[Mickaelh51]

Ex OK:

data_zero = 'zéro'
print(alpha2digit(data_zero, 'fr'))
0

Ex: NOK:

data1 = 'a a un trois sept trois trois sept cinq quatre zéro c c'
data2 = 'b b un trois sept trois trois sept cinq quatre zéro d d'
print(alpha2digit(data1, 'fr'))
print(alpha2digit(data2, 'fr'))
a a 1 3 7 3 3 7 5 4 zéro c c 
b b 1 3 7 3 3 7 5 4 zéro d d

We can see zéro is not transform to digit 0.

thanks in advance for your help
have a good day

idem for this example:
data_3 = 'sept un zéro'

result: 7 un 0
