I'm new to the arrow package in R and I'm having a trouble regarding special characters (Icelandic). I have a large data set and everything is fine until I write the file to disk and read it in again (i.e. I use write_parquet() and then read_parquet()). When I read the data back in to R special characters turn into question mark. I.e. Veitingastaðir becomes Veitingasta�ir.
This does not happen when I use .csv.
Is there anything I can do when I write the .parquet file to disk or when I read it in to prevent this?
