------------------------------

             Summary: [C++] CSV empty quoted string is treated as NULL
                 Key: ARROW-10115
                 URL: https://issues.apache.org/jira/browse/ARROW-10115
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
    Affects Versions: 1.0.1
            Reporter: Maciej


When parsing my CSV I have set
{color:#267f99}ConvertOptions{color}::s{color:#001080}trings_can_be_null to true.{color}

{color:#001080}Now as I have values:{color}
{code:java}
1234,"",345
{code}
{color:#001080}the string value which is an empty string is treated as NULL.
I've checkeced default valeus of {color:#267f99}ConvertOptions{color}::n{color}{color:#001080}ull_values and there is empty string considered null but it's not empty string it's quoted empty string which shouldn't be treated as NULL in my opionion. Simillar behavior we have in Postgresql empty quoted string is not treated as a NULL: https://www.postgresql.org/docs/12/sql-copy.html{color}
