Exporting CSV from Microsoft Office Excel with UTF-8 encoding results in a file with BOM at the beginning.
In order to handle Japanese correctly, we often use UTF-8 BOM in CSV output, but the current version does not work properly and we are troubled.
Sorry for the long delay in responding to this PR. Could you please attach a CSV with a BOM that doesn't work with the current code? It will help to add a test to make sure this functionality doesn't break again.
