解码� 真正的性格

Question

当我从twitter的Stream API读取数据然后写入xmlfile时.

但是一些特殊的角色�会导致错误(我的意思是当我在Chrome中打开xmlfile时,Chrome表示该角色出错了!)

我想�在写入xmlfile之前将编码序列()转换为真实字符( )!

怎么实现这个？

这是XMLFile内容:

<?xml version="1.0" encoding="UTF-8"?>

字符引用�表示代理代码点(U + D83D),因此尝试将其转换为字符是错误的.它不是一个角色,甚至不是半个角色.

您需要追溯到生成引用的位置.原因可能是字符编码混乱.在UTF-16中,代理代码单元可能出现但必须在数据被解释为字符时成对处理,例如转换为另一种编码或转换为字符引用.
