org.dom4j.DocumentException:Invalid byte 2 of 2-byte UTF-8 sequence

今天做工作流项目（jbpm4）,将流程文件导出成xml到客户端后，编码格式是utf-8的，在本地将导出的xml导入到mysql数据库中是正常的，但是将该项目打成war包后放到虚拟机中的tomcat中，运行虚拟机中的tomcat，并访问项目时候，导出的也是utf-8的xml文件，但是再将该文件导入到mysql数据库时候却出现下面的错误：

org.dom4j.DocumentException: Invalid byte 1 of 1-byte UTF-8 sequence. Nested exception: Invalid byte 1 of 1-byte UTF-8 sequence.  
    at org.dom4j.io.SAXReader.read(SAXReader.java:484)  
    at org.dom4j.io.SAXReader.read(SAXReader.java:321)

    at com.dataoperate.JdbcOp.insertDb(JdbcOp.java:30)  
    at com.dataoperate.JdbcOp.main(JdbcOp.java:89) 

google了一下找到了下面的解决方法：
将原先导出的流程xml文件中的编码格式由“utf-8”改成“gbk”后保存，再导入就可以了。
仔细分析原因，我的本地电脑用的是win 7 ，而虚拟机中的系统使用的想xp系统。在中文版的window下java的默认的编码为GBK，虽然我们标识了要将xml保存为utf-8格式但实际上文件是以GBK格式来保存的，所以这也就是为什么能够我们使用GBK、GB2312编码来生成xml文件能正确的被解析，而以UTF-8格式生成的文件不能被xml解析器所解析的原因。
给我解决思路的来源如chenyanbo所说：

下面是我的一个导出的流程xml文件：
