Until recently I have been able to download the wikidata JSON with a javascript routine without any problems. Lately the script seem to fail if there are any special characters in the page name. For instance, when I try:
https://www.wikidata.org/w/api.php?action=wbgetentities&sites=enwiki&titles=Krüppel&languages=en&format=json
the error message I get is this HTML:
<!DOCTYPE html> <html lang="en"> <meta charset="utf-8"> <title>Wikimedia Error</title> <style> * { margin: 0; padding: 0; } body { background: #fff; font: 15px/1.6 sans-serif; color: #333; } .content { margin: 7% auto 0; padding: 2em 1em 1em; max-width: 640px; } .footer { clear: both; margin-top: 14%; border-top: 1px solid #e5e5e5; background: #f9f9f9; padding: 2em 0; font-size: 0.8em; text-align: center; } img { float: left; margin: 0 2em 2em 0; } a img { border: 0; } h1 { margin-top: 1em; font-size: 1.2em; } .content-text { overflow: hidden; overflow-wrap: break-word; word-wrap: break-word; -webkit-hyphens: auto; -moz-hyphens: auto; -ms-hyphens: auto; hyphens: auto; } p { margin: 0.7em 0 1em 0; } a { color: #0645ad; text-decoration: none; } a:hover { text-decoration: underline; } code { font-family: sans-serif; } .text-muted { color: #777; } </style> <div class="content" role="main"> <a href="https://www.wikimedia.org"><img src="https://www.wikimedia.org/static/images/wmf-logo.png" srcset="https://www.wikimedia.org/static/images/wmf-logo-2x.png 2x" alt="Wikimedia" width="135" height="101"> </a> <h1>Error</h1> <div class="content-text"> <p>Our servers are currently under maintenance or experiencing a technical problem.

However, when I try something without any special characters like:
https://www.wikidata.org/w/api.php?action=wbgetentities&sites=enwiki&titles=Actinia&languages=en&format=json
it returns the JSON code just fine.
