Java write utf-8 bom to file

Then I tried to read content of 2 files and as expected saw that file generated by notepad contains 3 bytes prefix:. Bottom line: write these 3 bytes before writing the content. Unfortunately, CSV is a very ad hoc format with no metadata and no real standard that would mandate a flexible encoding.

Thats a known problem. The actual encoding used depends on the locale settings of Microsoft Windows. You could create an Excel file containing some persian characters and save it as an CSV file. Then write a small Java program to read this file and test some common encodings.

See here for the details, including some guidelines on when and where to use it. If you are trying to view the csv file in Windows, this is probably a valid use of the BOM.
