Migrate to CKEditor 5 for Drupal 9.4+ / Drupal 10

I have Drupal 10 installed. When migrating it from one domain to another, the CKeditor stopped working. How can I repair it?
Thnks a lot!

@natiar do you have any javascript or other errors?

Giving this a test using the plain diff as a patch. In Drupal 9.5.9 with CKeditor5 enabled the Special Chars does not appear in the plugins area of the Text Format configuration as it does with CKeditor4.

I may be missing something in the implementation, and there may not yet be enough mods for it to work, but I thought you'd appreciate the feedback.

@jodavidson yep, still work in progress 😜

Just researching the more accurate way to upgrade it as special characters are now included in the core so only modification part is required:

1. Create JS file with behaviour, get all instances of CKEditor and loop through them by applying newly defined special characters and insert it via ckeditor_specialchars_library_info_alter().
2. OR create CKEditor JS plugin as specified in CK documentation and then insert it to existing specialCharacters plugin via ckeditor_specialchars_ckeditor5_plugin_info_alter(). Another issue with the second solution is that current webpack config gives cannot parse CSS error.
