### What problem does this PR solve? Issue Number: close #66993 Problem Summary: When a user creates a JDBC catalog for MySQL/OceanBase and explicitly sets characterEncoding in the jdbcUrl, the FE previously still forced characterEncoding=utf-8, overriding the user choice and sometimes duplicating the parameter. This change makes checkAndSetJdbcParam respect any user-provided value: it only appends the utf-8 default when the parameter is absent. ### Release note None ### Check List (For Author) - Test: Unit Test (JdbcResourceTest) - Behavior changed: No - Does this need documentation: No -- This is an automated message from the Apache Git Service.
