      14848215 - RANDOM PASSWD IN "MYSQL_INSTALL_DB" FAILS DUE TO "TR": "ILLEGAL BYTE SEQUENCE"
      
        Follow-up fix: setting LC_CTYPE was not enough on all platforms.
        On Solaris, with my settings, I saw it generate password with only
        digits or 'a'.
      
        Fixed by setting LC_ALL=C instead.

      Bug#11762933: MYSQLDUMP WILL SILENTLY SKIP THE `EVENT` TABLE DATA IF DUMPS
      
      Post-push fix: Drop event explicitly since events are now dumped even with --skip-events
