Improvement suggestion: prepend BOM to CSV

[Myrmex]

Hi, I'm using this code and when I open the file with the default CSV handler, which like in several other machines happens to be Excel, I get garbage characters instead of my Unicode characters. Yet, the CSV is built correctly and I can see it if I save it before opening. This is a known issue for Excel, and the workaround is prepending the CSV with the BOM code, by changing your code at line #20 to data = '\uFEFF'; instead of just data='';. This way, any modern version of Excel (probably above 2003) opens the file correctly. Maybe you could consider integrating this change into your code.
Thank you!
