            Bug ID: 29287
           Summary: percent-decoding by W3C caused false report
           Product: Validator
           Version: HEAD
          Hardware: PC
               URL: http://cold32.com
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: check

  Target Milestone: ---

The W3C Link Checker, when I entered <http://cold32.com>, allowed 10 levels of
recursion (more than needed), and set it to send the Referer, reported a fault
but it was caused by the link checker's own fault. A link in
http://cold32.com/image-credit.htm for
https://en.wikipedia.org/wiki/Yup%27ik_clothing#/media/File:Eskimos_woman_and_girl_ice_fishing.jpg
was interpreted by W3C as
https://en.wikipedia.org/wiki/Yup'ik_clothing#/media/File:Eskimos_woman_and_girl_ice_fishing.jpg
(interpreting "%27" as "'") but W3C said that was redirected to
https://en.wikipedia.org/wiki/Yup%27ik_clothing#/media/File:Eskimos_woman_and_girl_ice_fishing.jpg
(interpreting "'" as "%27"). If the Link Checker had not percent-decoded one
character, no error would have been reported, because the URL on my page and
the destination URL were identical but W3C's was not.

For this bug report, I guessed the component and the version; the version is
actually 4.81.
