I've been reading about how to handle Google requested URL here
There is an example from Google :
- Pretty URL:
- Ugly URL:
As you can see, in the ugly URL there is "%26" characters, as explained by Google that they need to be unescaped by the web server to obtain the original URL:
%00..20 %23 %25..26 %2B %7F..FF
As in the example, the "%26" (ugly URL) represents the "&" (pretty URL), so in this case, we need to replace "%26" with "&" to get the original URL.
How do we know which character is represented by the special characters that Google replaced?
