In

https://en.wikipedia.org/wiki/Comma-separated_values

it says:

"Also, many regional versions of Excel will not be able to deal with Unicode in CSV."

and

"One simple solution when encountering such difficulties
is to change the filename extension from .csv to .txt;
then opening the file from an already running Excel instance
with the "Open" command, where the user can manually specify
the delimiters, encoding, format of columns, etc."
