The title of the page is:
盾之勇者成名录 (legacy)
盾之勇者成名錄 (parsoid)
盾之勇者成名錄 (in database)
The last character is different. It looks like we're just not language-converting the title, although https://zh.wikipedia.org/w/index.php?title=%E7%9B%BE%E4%B9%8B%E5%8B%87%E8%80%85%E6%88%90%E5%90%8D%E9%8C%84&action=info&uselang=en seems to indicate there's a displaytitle being set. I can't find -{T|... in expandtemplates output or data-mw-variant='{"title" or displaytitle in the Parsoid HTML, so I think this is the default displaytitle generation which is at fault.
