As I understand it, all perl strings have a UTF-8 flag, which is either on or off. perl tries to store strings as ascii characters(single byte) as long as it can, then perl turns the UTF-8 flag on when it realizes there are multi-byte characters present.
In my opinion, the docs are poorly written because they seem to use the terms Unicode and UTF-8 as if they are equivalent--and they are different things. A case in point is your quote. I think that quote is referring to the Unicode code point. 2**31 is roughly the highest integer that can be represented by 4 bytes (= 32 bits).
