[jira] [Commented] (ARROW-12510) [C++][Python][CSV] Allow quoted values to be null

    [ https://issues.apache.org/jira/browse/ARROW-12510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17330376#comment-17330376 ] 

Joris Van den Bossche commented on ARROW-12510:
-----------------------------------------------

Would this then only work for columns that are not inferred as string? (or specified as string through an explicit column_types) 
Because for string there would be no distinction between empty string or null.
