What is the motivation for defaulting bom = false in CSV.write ?

I just noticed, that on Windows, when I write a CSV and open it with Excel (which seems frequent use case), "ä" and similar are not displayed correctly.

I guess that means excel requires a BOM character in order to understand UTF8? When I import a csv, I have the option to choose a "file origin" and can select UTF8 from the list. Maybe that would resolve your issues? Writing the BOM character by default would be breaking and is kind of a legacy technique in the world these days.

Ah ok. I did not realize this would be breaking. Fine for me.
I was referring to opening by double click. This does not prompt any dialog wrt encoding (or delimiter).
