我们有一个使用XML与服务器通信的移动客户端.当我们需要发送一些最近的UTF-8表情时,我遇到了一个问题,这些表情很容易在新手机上使用.例如: .

现在,我的Android应用程序没有编码和发送它的问题,但在服务器端,事情往往有点爆炸性.

如果我们尝试使用上面的任何一个表情发送消息,我们会得到一个巨大的堆栈跟踪,相关部分:

javax.xml.transform.TransformerException: org.xml.sax.SAXException: Invalid UTF-16 surrogate detected: d83d d83d ?
java.io.IOException: Invalid UTF-16 surrogate detected: d83d d83d ?

        at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerImpl.transform(Unknown Source)

如果我们试图解析它:

在这种情况下,XML是:

<?xml version="1.0" encoding="UTF-8"?><action>
<set>
<absence requestid="0" from="2017 01 13 13 00 11" to="2017 …
