There is some value in having a single code path, even if that means double-escaping, so I'm not too concerned about the doubling up. %22 or %5C are both valid ways to express those characters as it is, so you can avoid the two-pass encode easily. Either way, doing both at once is fine.
The other options draw more from programming language syntax, which might be nice, but the first is less efficient in a lot of cases; the second seems fine.
