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?

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。

我们使用了以下方法:

转换CSV到UTF-16 LE 在文件开头插入BOM 使用制表符作为字段分隔符

首先将Excel电子表格保存为Unicode文本。使用ie浏览器打开TXT文件，点击“另存为”TXT编码-选择合适的编码，例如Win Cyrillic 1251

office 365的工作解决方案

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);

找到了ASP的解决方案。使用POM下载UTF8格式的CSV文件:

byte[] csvBytes = Encoding.Default.GetBytes(csvString);
UTF8Encoding utf8 = new UTF8Encoding(true);
byte[] bom = utf8.GetPreamble();
var result = bom.Concat(csvBytes).ToArray();
return new FileContentResult(result, MediaTypeHeaderValue.Parse("text/csv; charset=utf-8"));

Excel是识别下载的CSV文件而不是UTF8。

这并不是准确地解决问题，但由于我偶然发现了这一点，上面的解决方案不适合我或有要求，我不能满足，这里是另一种方式添加BOM时，你可以访问vim:

vim -e -s +"set bomb|set encoding=utf-8|wq" filename.csv
