Code points for alternate glyphs

Sorry if this is a bit of a basic question, but I'm wondering what the code point should for alternate glyphs? For example, let's say I have glyph A and I also have glyph A.ss01. What should the unicode value be for A.ss01? Should it be the same as A? Should it have a code point at all?

    In general, no. Giving PUA code points to alternate glyphs is bad practice because when the alternate is used it changes the text, which means the text has to be re-typed to use it with other fonts. However, if you’re designing display fonts for the scrapbook crowd they’ve come to expect PUA encoded fonts for use in software that wasn’t designed for accessing alternate glyphs.

    Very grateful to both of you for sharing your thoughts. It gives me the clarity and direction I needed.
