Question

I am dynamically creating CSV files using C#, and I am encountering some strange encoding issues. I currently use the ASCII encoding, which works fine in Excel 2010, which I use at home and on my work machine. However, the customer uses Excel 2007, and for them there are some strange formatting issues, namely that the ‘£’ sign (UK pound sign) is preceded with an accented ‘A’ character.

What encoding should I use? The annoying thing is that I can hardly test these fixes as I don’t have access to Excel 2007!

I’m using Windows ANSI codepage 1252 without any problems on Excel 2003. I explicitly changed to this because of the same issue you are seeing.

private const int WIN_1252_CP = 1252; // Windows ANSI codepage 1252

this._writer = new StreamWriter(fileName, false, Encoding.GetEncoding(WIN_1252_CP));
