Not handling the encoding of "reserved Character" if it is there in the object name.

I tried to delete the object which was having '%' in its name. I observed that while creating the URL, this % is not getting encoded properly and hence the deletion was failing.

i.e. Object is "abcd%20-%20xyz/12"
% should get encoded and the URL should contains the object name as "abcd%2520-%2520xyz/12"

I am not aware if all of the reserve characters are handled or not.
