Answer 1

Unless your strings are limited in some way or your integers hold more bits than the strings you're trying to convert, you cannot guarantee the uniqueness.

Let's say you have a 32 bit integer and a 64-character character set for your strings. That means six bits per character. That will allow you to store five characters into an integer. More than that and it won't fit.
