@lukapeschke Can we provide an option to parse these special symbols as a string and retain in the sheet please? Now, it removes the symbol and puts null there.
Thank you.

@durgeksh could you please create a separate issue for that ? I'll mark it as a feature request

@durgeksh It's not that simple because if it's considered as a string then it can mess up with the rest of the column that would have another type
So it requires either everything to be casted as a string or some kind of union type on the column.
Anyway it's definitely a feature request!

@PrettyWood Yes, in that case safe typecast would be string for the column with special symbols.
