Question

我正在通过SAX解析器运行一些XML，并注意到解析器无法正常运行某些字符作为数据内容。 XML应该是UTF-8编码，SAX解析器设置为处理该编码。

缩小有问题的字符串并在十六进制编辑器中查看XML文件我可以看到例如2C10导致问题，如果我将其改为C2A2（维基百科上给出的示例字符），那么SAX解析器可以工作。那么2C10不是有效的UTF8字符吗？

Answer 1

UTF-8 page on Wikipedia意味着2C10将被解释为,，后跟控制代码DLE（数据链接转义，显然）。在XML中出现在CDATA块之外的控制字符似乎不合适！

U + 2C10是GLAGOLITIC CAPITAL LETTER NASHI。这是它的属性：
