title: UTF8 to Base 2 Representation Swift
body: <p>I was wondering what is the best way for converting an UTF8 Array or String to its base 2 representation(each UTF8 value of each character to its base 2 representation) . Since you could have two values representing the code for the same character, I suppose extracting values from the array and then converting it is not a valid method. So which one is? Thank you!</p>
