I wrote a custom toolbar in order to select export formats. The toolbar works fine with PDF and RTF formats, but there is a problem with CSV format when the report contains characters like à, è, é, etc. or symbols like u20AC. In that case the symbols are not displayed correctly and there are problems importing the CSV file in Excel (I have to replace with a text editor the wrong characters in the file exported). The problem is verified also using the standard Crystal Reports toolbar and only for CSV format: PDF and RTF reports are created correctly.
I had a similar problem with JSP, but the solution was the page charset. In this case, how can I solve the problem?
