Antoine Pitrou commented on ARROW-6934:
---------------------------------------
Well, there's nothing special about utf8 columns except that they are marked as
utf8. Under the hood it's binary data just as in a binary column.
So you should be fine using a binary column.
> [Python] Choose string column encoding in csv reader

> Key: ARROW-6934
> URL: https://issues.apache.org/jira/browse/ARROW-6934
> Project: Apache Arrow
> Issue Type: Wish
> Components: Python
> Reporter: Sascha Hofmann
> Priority: Major
>
> I was wondering whether there is a possibility to provide a different
> encoding for string columns in the parse option of the csv reader in pyarrow.
> I saw that there is a check whether or not a column is utf8 encoded. The
> default seems to be that if that turns out to be false the column is
> interpreted as binary.
> Is there any way to have a fallback option, meaning if the check_utf8 is
> false then maybe try latin-1 before turning to binary?
