## Bug Report
### Which version of ShardingSphere did you use?
ShardingSphere5.1
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
Execute `SELECT COUNT(*) AS total FROM (SELECT DISTINCT rtu.topicset_id FROM
relate_topicset_usergroup rtu JOIN relate_usergroup_user ruu ON
ruu.usergroup_id = rtu.usergroup_id WHERE ruu.account_id = 1183367845602394287)
u LEFT JOIN topicset_info ti ON u.topicset_id = ti.topicset_id LEFT JOIN
relate_label_topicset tl ON ti.topicset_id = tl.topicset_id LEFT JOIN
teacher_info ti2 ON ti.account_id = ti2.account_id LEFT JOIN unit_first_info
ufi ON ufi.unit_first_id = ti.unit_first_id WHERE (ti.topicset_recycled = 1 OR
ti.topicset_recycled = 3 OR topicset_recycled = 0) AND ti.topicset_name LIKE
CONCAT('%', '测试', '%') AND ti.topicset_typeid = 4`successfully.
### Actual behavior
`[ERROR] 2024-04-24 22:37:49.860 [ShardingSphere-Command-9]

### Reason analyze (If you can)
It may be that ShardingSphere-Proxy cannot use 'ISO-8859-1' to encode
Chinese and needs to change the encoding format.
