# This test evaluates that when donor and joiner have a different server
# character set, recovery through clone will fail and will fall back to
# incremental recovery.
#
# 1. Install clone and keyring plugins on server1.
# 2. Bootstrap server1 and add some data
# 3. Restart server 2 with a monitoring process (mysqld_safe) if needed
# 4. Install the clone plugin on server2.
# 5. Set server character set to latin1 (non-default)
# 6. On a empty server2 start group replication
#    Clone will fail since the donor server character set utf8mb4 (default) is
#    different from joiner character set. Recovery will fallback to incremental.
# 7. Cleanup
