MrArmonius a53641e773 Correct the function GenerateName
The problem was the encode in `name += string(alphabet[])`
It takes only 1 byte but the characters like 'è','@' are encoding
on several bytes (1 to 4 bytes).
The better solution was to create a slice of string, like this
we don't have problem about take only one byte instead of 2,3 or 4
bytes.
