Issue validating with spaces and letters

[emafriedrich]

We have a issue regarding validations with strings that has spaces and letters

> const v = require('cpf-cnpj-validator')
> v.cpf.isValid('   16704533672     d ')
true
> v.cpf.isValid('   16704533672     ')
true
> v.cpf.isValid('   16704533672     asdfasdfasdf')
true
> v.cpf.isValid('   16704533672     asdfasdfasdf as34343434')
false
> v.cpf.isValid('   16704533672     asdfasdfasdf as3')
false
> v.cpf.isValid('   16704533672     asdfasdfasdf asasdfasdf asdfasdf asdf asdf asdfasdf')
true
> v.cpf.isValid('asdfasdf16704533672asdfasdf')
true

We consider this as a big issue. You will know if is intended this behavior.

Just to let you know.

Thanks

isValid only validates the digits in the string by default.

If you need those to fail, you may send a second parameter called strict, for stricter validation. It will return false if there are any non-digit characters, except "." and "-", which are ignored.

example: v.cpf.isValid(value, false).
