U4-9584 - Backoffice stops working if a cookie is set and contains one of the following characters "å", "ä" or "ö"

Duplicates: U4-9873

We track form interaction on one of our websites and set cookies depending on user action, and I noticed that when a cookie is set containing either "å","ä" or "ö" I get 417 "(Missing token null)" and everything in the backoffice stops working.

Clearing the cookie and then reloading the backoffice makes it work again.

To reproduce, login to umbraco and set a cookie in console, "document.cookie = "cookie with å";" then reload the page.

I'm consolidating all the 417 errors into U4-9873.
