Note:
When specifying a URL in code, any special characters (characters other than letters and numbers) need to be encoded. For example, a space character is encoded as %20.

(Browsers typically take care of encoding URLs entered into the address bar--so the URL displayed after visiting a page may differ somewhat from the one that was initially entered.)

Here are some typical encodings:

space
+
%
%20 or +
%2B
%25

So:

Instead of Use

& (A&B)
space (A B)

%26 (A%26B)
%20 (A%20B)
