我有一个非常简单的东西，它只是输出一些CSV格式的东西，但它必须是UTF-8。我在TextEdit或TextMate或Dreamweaver中打开这个文件，它会正确地显示UTF-8字符，但如果我在Excel中打开它，它会做这种愚蠢的íÄ之类的事情。下面是我在我的文档头部得到的内容:
header("content-type:application/csv;charset=UTF-8");
header("Content-Disposition:attachment;filename=\"CHS.csv\"");
这一切似乎都达到了预期的效果，除了Excel (Mac, 2008)不想正确地导入它。Excel里没有“以UTF-8格式打开”之类的选项，所以……我有点烦了。
我似乎在任何地方都找不到任何明确的解决方案，尽管很多人都有同样的问题。我看到的最多的事情是包括BOM，但我不知道如何做到这一点。正如你所看到的，我只是回显这些数据，我没有写入任何文件。如果我需要，我可以这样做，我只是没有因为在这一点上似乎不需要这样做。任何帮助吗?
更新:我尝试将BOM作为回显包(“CCC”，0xef, 0xbb, 0xbf);这是我刚刚从一个试图检测BOM的网站上找到的。但Excel只是在导入时将这三个字符附加到第一个单元格，仍然会把特殊字符弄乱。
