I load attached Excel file, and save it as CSV file. All characters are not displayed correctly in result CSV file. The texts in original Excel file is Chinese, and in Chinese font “宋体”, which is not available on my Windows system. But the file is displayed correctly when I open it in Excel.
Workbook wb = new Workbook(buf);
Could you please try this latest fix/version: Aspose.Cells for Java v184.108.40.206 and let us know your feedback.
I have tested your code with your sample file a bit, it works fine I think.
If you still find any issue, please do provide your generated CSV file and your expected CSV file (you may save it as in MS Excel manually) here. We will check it soon.
