I have successfully installed google recaptcha v3 on my site and there is some strange thing: it works fine on every url like "site.com/url" or "site.com/url.php" or "site.com/url.html" but it does not work on url that contents url-encoding symbols like site.com/%FE.html. What can be the reason of this problem? By the way, %FE is russian "ю" symbol in windows-1251...Recaptcha can't work with this url-encoded symbols?

question from:https://stackoverflow.com/questions/65916958/google-recaptcha-v3-is-not-showing-if-url-contents-url-encoding

So, i have found the right solution. Recaptcha v3 uses decodeURIComponent function to work with urls, so it can't decode urls (throwing an error 'URI malformed'), that were encoded with URI-encoding. Now i use encodeURIComponent for generating my urls and everything works good.

For example, encoded russian letter 'ю' with encodeURIComponent is "%D1%8E" (while it is "%FE" in url-encode)
