Problem:
We from Switzerland have signs like "Ö", Ü, Ö and those chars are also stored in our fields in our MongoDB

In our application all works fine with that "special chars". While reading from DB and Saving everything works fine...

But not in CSV exports.

I'm exporting my docs successfull to csv over CLI with:
mongoexport --host xy.mongohq.com --port 10082 --username XY --password XY --db appXY --collection moment --csv --out /Users/millien/Projects/amag/_export/contacts.csv --fields name,email,ip,text,createdAt,isVisible

In the exported CSV every special sign (Ö,Ä,Ü and others) are replaced with not readable chars like
Ü = FÌ_nf

Seems to be an encoding problem.
Can you help us? Is there a way to set encoding of exports? I didn't find something.

Thanks and best regards from Switzerland
