How can I get CSV file encoding UTF-8 in C#.Net?

Question

I wanna make CSV file encoding UTF-8. Now, my CSV file cannot show Japanese Fonts. I want C# code to solve this problem.

SuSanda,
I'm not sure about your current code or your actual text you're trying to save, but this might get you in the right direction.

using(var sw = new StreamWriter("testfile_utf8.csv", false, Encoding.UTF8))
{
    sw.WriteLine("頼もう");
}

If you open that file in Excel, it will show the Japanese text as expected.
If you do not include the Encoding.UTF8 parameter, it will display gibberish.

I hope that's what you're looking for.
