Decode it all, and then encode it.

The best solution is going to be to better manage where you are getting the different components of your url, and not mixing and matching encoded and unencoded strings. Your post is confusing as well in that the entire url you listed is encoded. That is to say, there are no elements of that url that are not ASCII.
