Uncaught URIError: URI malformed with reCAPTCHA

On some pages that have an encoded part in the url, like %FC instead of ü, I get a Uncaught URIError: URI malformed error in the console and the captcha therefore is not working.

Our Project is iso-8859-1 encoded and there is nothing I can change about that.

Do you know a workaround that could fix this? I'm using reCAPTCHA 2.

Solution

  • My solution now is, that before the recaptcha/api.js is executed, I grab the window.location.pathname, get rid of the problematic elements and exchange it in the url with history.pushState. If I'd simply changed the window.location.pathname a page redirect would be the consequence.

    Here is my example code:

    var oldPath = window.location.pathname;
var newPath = decodeURIComponent( unescape( unescape(oldPath)));
var stateObj = {};
history.pushState(stateObj, "", newPath);
