The reason is because the problem encoding your database is not utf-8, then when you build the table did not specify the default encoding is utf-8 table
Solution 1: If the operation object data stored by throwing an exception when you save
1. Deletion of the table, with ENGINE = InnoDB DEFAULT CHARSET = utf8 words, for example:
drop TABLE table name CASCADE;
the CREATE TABLE table name ( the serialNo VARCHAR (50) the COMMENT 'serial number', pdesc the TEXT the COMMENT 'text', EDSInputtime VARCHAR (20 is) the COMMENT 'timespan'
) ENGINE = the InnoDB the DEFAULT the CHARSET = UTF8 the COMMENT = 'Detail';
2. If you can not delete the table, direct execution
alter table cb_arbitration engine=innodb;
alter table cb_arbitration CHARSET=utf8；
or
ALTER TABLE `表名` DEFAULT CHARACTER SET utf8;
Solution 2: If the abnormality patterning saved, will be changed to the appropriate column to utf8-utf8_general_ci
