Address Line1 must contain different special characters based on country using autocomplete rule

Summary:

We have a requirements says if Address Line1 contains one or more digits, then it must be directly followed by:

a) for German addresses (if country=DE): either a letter, a dot, a blank or a hyphen. 

b) If country is not DE, then either a letter, a dot, a blank, a hyphen, a comma or a slash.

How can we write autocomplete to achieve this?
