根据联通sgip1.2接口协议，使用华为短信开发包，报错
[Fatal Error] :24:28: An invalid XML character (Unicode: 0xd863) was found in the element content of the document. org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0xd863) was found in the element content of the documen.报错原因：xml的编码格式是unicode，读取失败
解决办法：解压smproxy.jar包，然后找到华为短信开发包\CMPP3资料\smproxy\com\huawei\insa2\comm\sgip下有一个resource_zh.xml，这个文件的编码格式改成utf-8，保存时业保存成utf-8，然后重新打包，就不会报错了
