 {{{
 #!CommitTicketReference repository="" revision="61405"
 Export: Fix fatal error when passing `null` to `wxr_cdata()` by casting
 passed value to `string`.

 This ensures that `wp_is_valid_utf8()` does not cause a type error since
 it only accepts strings.

 Developed in https://github.com/WordPress/wordpress-develop/pull/10595

 Follow-up to [60630].

 Props hbhalodia, westonruter, desrosj, albigdd, jorbin.
 See #38044.
 Fixes #64347.
