Getting hit by invalid URLS

I am getting hit by URLS that do not exist in our database resulting in a lot of 404s.


The above URL does not exist in our database we do have :ãrder-25463-02-2

So Cloudflare is encoding the ã hence resulting in a 404. Why is it doing that in fact why is it even hitting my site. I know its Cloudflare because I checked multiple IPS and they are go back to Cloudflare.

How to sort it out?
