I don't think this is the right approach. With this change, "%%20" will be
encoded to "%25%20", right? What if "%%20" was not encoded string? It should be
encoded to "%25%2520".
Shouldn't we make sure that all callers of this function pass decoded URLs?
Another options is to abort encoding and return inputs as outputs if input
URLs seem to be already encoded. It can't handle mixed cases but I think it
would't happen. (If it happens, it should be a bug.)
