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。

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。

其他回答

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();
}

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

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

Alex是正确的，但是由于你必须导出到csv，你可以在打开csv文件时给用户这样的建议:

另存为csv格式打开Excel 使用“data”导入数据——>导入外部数据——>导入数据选择文件类型“csv”并浏览到您的文件在导入向导中将File_Origin更改为“65001 UTF”(或选择正确的语言字符标识符) 将分隔符更改为逗号选择要导入的位置并完成

这样特殊字符才能正确显示。

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。
