We are generating CSV reports using Jasperreports 5.0.1. The reports are UTF-8 encoded. However, when we download the report, the report opens in Excel using the file association, but the Japanese characters are not rendered. For example instead of 市場取引 we see å¸‚å ´å–引. Our locale is en_US on Windows 7. In locale ja_JP, the Japanese characters are improperly rendered. If we download the report and open in any text editor, the characters are showing correctly. Any idea, what is going on? Thanks in advance.
