Describe the bug
using JDBC driver on Mariadb, creates empty tables and references a column 'u' that is not in the query.
it just creates an empty table in mariadb and gives a java.sql.SQLException (cfr screenshot below)

It looks like Drill's JDBC writer needs to gain support for Unicode escape sequences in its input data.

To Reproduce
Steps to reproduce the behavior:

  • inject a 'tab' character (or any other unicode character) are present in the content
    cfr query in screenshot

Expected behavior
when there are unicode characters in varchar columns written to a table via a JDBC connection, it should create the table and populate that table by supporting unicode data loading into the sql database table
