Comment (by hellofromTonya):

 Replying to [comment:6 SergeyBiryukov]:
 > On a closer look, it appears that `Normalizer::FORM_C` is the default
 value both for [https://www.php.net/manual/en/normalizer.isnormalized.php
 normalizer_is_normalized()] and
 [https://www.php.net/manual/en/normalizer.normalize.php
 normalizer_normalize()], so perhaps we can just remove it. That way the
 polyfilled function should work.

 That's a good point! Core doesn't need to pass the default `$form` value
 since both functions include the default in their function parameters.
 Then if the `intl` package is not available, the polyfill handles it.

 [attachment:"56980.2.diff"] should work.

 @SergeyBiryukov how can this be tested?
