是否可以强制Excel自动识别UTF-8 CSV文件?

I'm developing a part of an application that's responsible for exporting some data into CSV files. The application always uses UTF-8 because of its multilingual nature at all levels. But opening such CSV files (containing e.g. diacritics, cyrillic letters, Greek letters) in Excel does not achieve the expected results showing something like Г„/Г¤, Г–/Г¶. And I don't know how to force Excel understand that the open CSV file is encoded in UTF-8. I also tried specifying UTF-8 BOM EF BB BF, but Excel ignores that.

有什么解决办法吗?

附注:哪些工具可能像Excel一样?

I have to say that I've confused the community with the formulation of the question. When I was asking this question, I asked for a way of opening a UTF-8 CSV file in Excel without any problems for a user, in a fluent and transparent way. However, I used a wrong formulation asking for doing it automatically. That is very confusing and it clashes with VBA macro automation. There are two answers for this questions that I appreciate the most: the very first answer by Alex https://stackoverflow.com/a/6002338/166589, and I've accepted this answer; and the second one by Mark https://stackoverflow.com/a/6488070/166589 that have appeared a little later. From the usability point of view, Excel seemed to have lack of a good user-friendly UTF-8 CSV support, so I consider both answers are correct, and I have accepted Alex's answer first because it really stated that Excel was not able to do that transparently. That is what I confused with automatically here. Mark's answer promotes a more complicated way for more advanced users to achieve the expected result. Both answers are great, but Alex's one fits my not clearly specified question a little better.

在最后一次编辑5个月后，我注意到Alex的答案不知为何消失了。我真的希望这不是一个技术问题，我希望现在不再有关于哪个答案更好的讨论。所以我认为马克的答案是最好的。

保存在UTF-16(无LE, BE) 使用分离器\t

PHP代码

$header = ['číslo', 'vytvořeno', 'ěščřžýáíé'];
$fileName = 'excel365.csv';
$fp = fopen($fileName, 'w');
fputcsv($fp, $header, "\t");
fclose($fp);

$handle = fopen($fileName, "r");
$contents = fread($handle, filesize($fileName));
$contents = iconv('UTF-8', 'UTF-16', $contents);
fclose($handle);

$handle = fopen($fileName, "w");
fwrite($handle, $contents);
fclose($handle);

Excel 2013中忽略BOM的错误似乎已经修复。我有同样的问题与西里尔字母，但添加BOM字符\uFEFF确实有帮助。

这是一个老问题，但我刚刚遇到过类似的问题，解决方案可能会帮助其他人:

同样的问题是，将CSV文本数据写入文件，然后在Excel中打开生成的. CSV，将所有文本转移到单个列中。在阅读了上面的答案后，我尝试了下面的答案，这似乎可以解决问题。

在创建StreamWriter时应用UTF-8编码。就是这样。

例子:

using (StreamWriter output = new StreamWriter(outputFileName, false, Encoding.UTF8, 2 << 22)) {
   /* ... do stuff .... */
   output.Close();
}

我过去也遇到过同样的问题(如何生成Excel可以读取的文件，以及其他工具也可以读取的文件)。我使用的是TSV而不是CSV，但同样的编码问题出现了。

我没能找到任何方法让Excel自动识别UTF-8，我也不愿意/不能给文件的使用者复杂的如何打开它们的指令。所以我将它们编码为UTF-16le(带有BOM)而不是UTF-8。大小是原来的两倍，但Excel可以识别编码。而且它们的压缩性很好，所以尺寸很少(但遗憾的是并非永远)重要。

您可以转换。csv文件到UTF-8与BOM通过notepad++:

在notepad++中打开文件。进入“编码→转换为UTF-8-BOM”菜单。进入菜单文件→保存。关闭记事本+ +。在Excel中打开文件。

在Microsoft Excel 2013 (15.0.5093.1000) MSO(15.0.5101.1000) 64位中工作，来自Microsoft Office Professional Plus 2013在Windows 8.1上，非unicode程序的区域设置为“德语(德国)”。

UTF-8字节顺序标记将提示Excel 2007+您正在使用UTF-8。(请看这篇SO帖子)。

以防有人遇到和我一样的问题，. net的UTF8编码类不会在GetBytes()调用中输出字节顺序标记。您需要使用流(或使用一种变通方法)来获取要输出的BOM。
