推荐答案

由于@Shadow Wizard在评论中建议，可能的原因是<！DOCTYPE之前的一些数据字符...> 声明。例如，通过获取有效的XHTML文档并在文档的最开始插入无中断空格字符（NBSP，U + 00A0）可以重现问题。但是，一开始，BOM的存在不会导致问题（至少不在IE 9上，几乎没有使用任何浏览器）。有大量隐形或几乎看不见的字符可能会导致问题。

As @Shadow Wizard suggested in a comment, the probable cause is some data character before the <!DOCTYPE ...> declaration. For example, the problem is reproducible by taking a valid XHTML document and inserting the no-break space character (NBSP, U+00A0) at the very start of the document. But the presence of a BOM at the start does not cause the problem (at least not on IE 9, hardly on any browser in use). There is a large number of invisible or barely visible characters that might cause the problem.
