There's unsafe and then there's <unsafe>. The URL BNF uses the term <unsafe> for a specific set of characters which have to abide by some rules, and the term <reserved> for some other characters which have different rules. The point is that '+' should be in the <reserved> set but not in the <unsafe> set. It's unsafe to use <reserved> characters too in situations where they are reserved, such as the query part of a URL after the ?. (It isn't unsafe to use them in other URLs). So, you're right, '+' is unsafe (in that context) but you're wrong, it's not <unsafe>.
