At this page, in the "Links" section, the "Links to this page" item links to https://en.wikipedia.org/w/index.php?title=Special:WhatLinksHere/Farrand%20&%20Votey%20Organ%20Company&hidetrans=1, which retrieves links to the page "Farrand", not "Farrand & Votey Organ Company". It's not urlencoding the '&'. Other links on the page are similarly affected.
