Issue with Redirect / RedirectPermanent with special characters #2106
Description
I think it was not an issue before my upgrade of .NetCore version. It might also just be a parameter issue.
I have some URL that redirect to URL with special characters, that throws an exception on handling.
After checking the Headers, it appears that the "Referer" header has the URL of redirection, and it contains these special characters.
Shouldn't it be either encoded, either do not throw exception?
Is it something I should handle manually or a "bug"?
An exemple of header:
Referer: https://mysite.com/Account/ExternalLoginConfirmation?returnurl=/City/København-DK
