I would probably be for the solution #2 and of course using the
unicode.runtime_encoding ini setting to convert it to binary.

I think this is a bad choice.. might not be useful to you, but might
be to some other people
I fail to see or imagine any useful usages for such hacks. Laziness
justifies it with binary strings (as in 5.x), but as long as an
unicode string is given, one should really first cast to integer
before using it with a bitwise operator (or any other non string
operation).
I'm in favour of keeping the current behaviors and drop the native
support as well for consistency (and documentation/wtf headaches).
