URL Encoding—Ampersand Problem

If you want to use Andaman & Nicobar in web API.

You can use instead of & you can use %26 and whole will be written as below.

Andaman+%26+Nicobar

It looks like the field is being encoded twice. First pass will result in & changed into %26, then urlencoding %26 will result in %2526, since the encoding for % itself is %25.
