To reproduce, go to <https://en.wikipedia.org/w/api.php?action=query&titles=%3C&format=jsonfm>. Everything after the < is colored blue, and the HTML is obviously invalid: [...] <pre style='white-space: pre-wrap;'> { "query": { "pages": { "-1": { "title": "<span style="color:blue;"><", "invalid": "" } } } } </pre> [...]

Well, the HTML is still invalid, though at least the tags should now be balanced. For example, <http://validator.w3.org/check?uri=https%3A%2F%2Fwww.mediawiki.org%2Fw%2Fapi.php%3Faction%3Dquery%26prop%3Drevisions%26rvprop%3Dcontent%26titles%3DAPI%3AMain_page%26format%3Djsonfm&charset=%28detect+automatically%29&doctype=Inline&group=0>: ---- Error Line 34, Column 2302: Bad value http://en.wikipedia.org/w/api.php?format=json&action=query&titles=Main%20Page&prop=revisions&rvprop=content\n for attribute href on element a: Illegal character in query: not a URL code point. …p;prop=revisions&rvprop=content\n">http://en.wikipedia.org/w/api.php?forma… Syntax of URL: Any URL. For example: /hello, #canvas, or http://example.org/. Characters should be represented in NFC and spaces should be escaped as %20. Error Line 44, Column 8: Stray start tag script. <script>if(window.mw){ ✉ Error Line 44, Column 8: Cannot recover after last error. Any further errors will be ignored. <script>if(window.mw){ ---- The aforementioned (comment 2) pretty-printing cleanup *should* fix these, though at the time of writing, the current version of the patch still adds the script element after the </html>.
