Redirect encoded URLs in Nginx
If you want to redirect https://www.example.com/%20 to https://www.example.com, with a 301 redirect in Nginx, add this to your configuration:
rewrite "^/ $" https://$host permanent;
This is only an example to redirects URLs that contain encoded characters. So you need to decode the characters to redirect the URLs.
Test the configuration with:
Reload Nginx with:
systemctl reload nginx
