urldecode ?

Answer 1

Well the thing with =3f and =3d is quoted-printable encoding. Ruby can decode it with the .unpack("M") method.

The backslashes? They're just weird and wrong. It would probably be safe to string-replace them to / since backslash should not be in a URL to begin with.

Answer 2

The equivalent of PHP's urldecode in Ruby is CGI::unescape.
