 > @SergeyBiryukov how can this be tested?

 I think we need to have a PHP compiled without the `--enable-intl` option,
 otherwise I'm afraid there is no way to disable this extension via
 php.ini.

 Plugins with the polyfill are found here:
 https://wpdirectory.net/search/01GGYGZXMMWWG4FDD3781EKW0W

 `remove_accents` is for example used if you create a new user, like
 described here:
 https://github.com/woocommerce/woocommerce/issues/35471#issuecomment-1301815362

 Non-NFC content can be found in #30130 (PDF attachment).

 So this could be a way to test.
