Comment:

 In [changeset:"31587"]:
 {{{
 #!CommitTicketReference repository="" revision="31587"
 When sanitizing a URL to redirect to, UTF-8 characters can be URL encoded,
 instead of being removed.

 While RFC 3986 does not specify which character sets are allowed in URIs,
 Section 2.5 states that octects matching UTF-8 character encoding should
 be percent-encoded, then unreserved octets outside of the UTF-8 range
 should be percent-encoded. As browsers tend to only implement support for
 UTF-8 in URLs, this change only implements the UTF-8 encoding part. We may
 revisit the second part if it becomes an issue.

 Fixes #31486
