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。

我正在从一个简单的c#应用程序生成csv文件，也遇到了同样的问题。我的解决方案是确保文件是用UTF8编码编写的，如下所示:

// Use UTF8 encoding so that Excel is ok with accents and such.
using (StreamWriter writer = new StreamWriter(path, false, Encoding.UTF8))
{
    SaveCSV(writer);
}

我最初有以下代码，其中口音在notepad++中看起来很好，但在Excel中被破坏:

using (StreamWriter writer = new StreamWriter(path))
{
    SaveCSV(writer);
}

你的里程可能会有所不同——我使用的是。net 4和Office 365中的Excel。

正如我在http://thinkinginsoftware.blogspot.com/2017/12/correctly-generate-csv-that-excel-can.html:上发表的

告诉负责生成CSV的软件开发人员纠正它。作为一个快速的解决方法，你可以使用gsed在字符串的开头插入UTF-8 BOM:

gsed -i '1s/^\(\xef\xbb\xbf\)\?/\xef\xbb\xbf/' file.csv

如果UTF-4 BOM不存在，该命令将插入。因此这是一个幂等命令。现在您应该能够双击该文件并在Excel中打开它。

这是我的工作解决方案:

vbFILEOPEN = "your_utf8_file.csv"
Workbooks.OpenText Filename:=vbFILEOPEN, DataType:=xlDelimited, Semicolon:=True, Local:=True, Origin:=65001

密钥是Origin:=65001

我尝试了我能在这个帖子上找到的一切，类似的，没有什么是完全有效的。然而，导入到谷歌表和简单地下载为csv工作就像一个魅力。如果你到了我的挫败点，可以试试。

下载并安装LibreOffice Calc 在LibreOffice Calc中打开您选择的csv文件谢天谢地，一个导入文本向导出现了…… .．.选择分隔符和字符编码选项在Calc中选择结果数据并复制粘贴到Excel中

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。
