用openfire搭建XMPP服务器时，客户端一发送emoji表情文字就会掉线，错误日志片段如下

可以看到，在MXParser.java的第384行，出了问题，这里是XML的合法性验证代码，因为emoji表情文字的编码不在合法的XML字符范围内，所以只要将这里改掉，就可以正常收发emoji了将MXParser.java中的more函数改为如下：

@Overrideprotected char more() throws IOException, XmlPullParserException {final char codePoint = super.more(); // note – this does NOT return a// codepoint now, but simply a// (single byte) character!if ((codePoint == 0x0)|| // 0×0 is not allowed, but flash clients insist on sending// this as the very first character of a stream. We should// stop allowing this codepoint after the first byte has// been parsed.(codePoint == 0x9) || (codePoint == 0xA) || (codePoint == 0xD)|| ((codePoint >= 0x20) && (codePoint <= 0xFFFD))|| ((codePoint >= 0xE000) && (codePoint <= 0xFFFD))|| ((codePoint >= 0x10000) && (codePoint <= 0x10FFFF))) {return codePoint;}throw new XmlPullParserException("Illegal XML character: "+ Integer.parseInt(codePoint + "", 16));}
