The character encoding of the document was not declared, and the encoding was guessable from content only late. This caused the document to be reloaded. The character encoding needs to be declared in the Content-Type HTTP header or using a byte order mark.
该文档未声明字符编码，因此编码是凭内容猜测出来的。这会导致文档被重新加载。字符编码需使用字节顺序标记（BOM），或是在 Content-Type HTTP 头中进行声明。
