Add test case of isDeterministic: Boolean = false.
> Support Unicode in codegen for SQL && TableAPI
> ----------------------------------------------
>
> Key: FLINK-8301
> URL: https://issues.apache.org/jira/browse/FLINK-8301
> Project: Flink
> Issue Type: Improvement
> Components: Table API & SQL
> Reporter: Ruidong Li
> Assignee: Ruidong Li
>
> The current code generation do not support Unicode, "\u0001" will be
> generated to "\\u0001", function call like concat(str, "\u0001") will lead to
> wrong result.
> This issue intend to handle char/varchar literal correctly, some examples
> followed as below.
> literal: '\u0001abc' -> codegen: "\u0001abc"
> literal: '\u0022\' -> codegen: "\"\\"
