    Description

      Probably same as on mysql
      https://bugs.mysql.com/bug.php?id=97103

      After changing column from from utf8mb4_unicode_ci to utf8mb4_bin - my unique composite key index stopped working (no results with index, but If I skipped index - it returned results). Had to run "recreate + analyze" for it to work again.
