Subject [jira] [Created] (FLINK-7451) Query fails when non-ascii characters are used in string literals

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

             Summary: Query fails when non-ascii characters are used in string literals
                 Key: FLINK-7451
                 URL: https://issues.apache.org/jira/browse/FLINK-7451
             Project: Flink
          Issue Type: Bug
          Components: Table API & SQL
            Reporter: Jark Wu
            Assignee: Jark Wu


I found that using non-ascii characters in string literals causes calcite planner to throw
the following exception:

{code}
org.apache.calcite.runtime.CalciteException: Failed to encode '%测试%' in character set
'ISO-8859-1'
{code}

The query is 

{code}
SELECT * FROM T WHERE f0 LIKE '%测试%'
{code}

The reason for the issue is that calcite uses latin encoding ('ISO-8859-1') by default. In
order to pass non-latin characters we should use unicode encoding as default.
