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。

一个真正令人惊叹的答案列表，但由于还缺少一个非常好的答案，我在这里提到它:打开谷歌表的csv文件，并将其保存到本地计算机作为excel文件。

与微软相比，谷歌已经成功支持UTF-8 csv文件，所以它只是在那里打开文件。导出到excel格式也可以。因此，尽管这可能不是所有人的首选解决方案，但它是非常安全的，点击次数也不像听起来那么多，特别是当您已经登录到谷歌时。

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。

是的，这是可能的。正如之前多个用户所指出的，当文件以UTF-8编码时，excel读取正确的字节顺序标记似乎存在问题。对于UTF-16，它似乎没有问题，所以它是UTF-8特有的。我为此使用的解决方案是添加BOM，两次。为此，我执行了两次下面的sed命令:

sed -I '1s/^/\xef\xbb\xbf/' *.csv

，其中通配符可以替换为任何文件名。然而，这会导致.csv文件开头的sep=发生突变。然后，.csv文件将在excel中正常打开，但在第一个单元格中有一个带有“sep=”的额外行。 "sep="也可以在源文件的.csv中删除，但是当用VBA打开文件时，应该指定分隔符:

Workbooks.Open(name, Format:=6, Delimiter:=";", Local:=True)

格式6是.csv格式。将Local设置为true，以防文件中有日期。如果Local未设置为true，日期将被美国化，这在某些情况下会破坏.csv格式。

在php中，你只需要将$bom前置到$csv_string:

$bom = sprintf( "%c%c%c", 239, 187, 191); // EF BB BF
file_put_contents( $file_name, $bom . $csv_string );

使用MS Excel 2016, php 7.2.4进行测试

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);
