Jira restore from XML

I've been doing a migration from a jira to another, The problem comes in when I try to restore data from xml :
Error importing data: org.apache.commons.lang.exception.NestableException: com.atlassian.jira.exception.DataAccessException: org.ofbiz.core.entity.GenericEntityException: while inserting: [GenericEntity:Action][id,10004][body,已解决][author,wangkai][created,2011-05-06 21:50:39.0][issue,10010][type,comment] (SQL Exception while executing the following:INSERT INTO jiraaction (ID, issueid, AUTHOR, actiontype, actionlevel, actionbody, CREATED, actionnum) VALUES (?, ?, ?, ?, ?, ?, ?, ?) (Incorrect string value: '\xE5\xB7\xB2\xE8\xA7\xA3...' for column 'actionbody' at row 1))
