Third-party services or plugins hardly appreciate accents, diacritical marks and special characters: it often results in errors that interrupts the exchange.
To increase the chance your page goes up in search engine results, it is highly recommended to make your URL similar to your page's title.

You can clean any string in 4 different ways.

However, in its native URLs, Bubble also keeps those unwanted characters the search engines may not understand properly.

The "Cleanup REGEX Url-SEO & API Optimizer" plugin helps you clean any character string (text) in two different ways, so that you can use the one you need for your purpose :

1 - removing accents and replacing unwanted characters with spaces or capitalized letters (cleanup_string)
