Chinese message is not correct?

I use strope.js and openfire 3.10.2 to set the web chat system.

But when i send chinese message,it is wrong and send English letter is right.

I open the warn.log file of the openfire it shows "'org.xmlpull.v1.XmlPullParserException: end tag name must match start tag name from line 1 (position: TEXT seen …\u5bf0\ufffd/body>… @1:202)
