Passing Chinese characters in SQL statement in EDS

Issue

• Is there any additional setup / configuration need to be done in EDS to support chinese characters in the SQL statement ?

We are running below SQL statement in SQuirrel SQL statement

select * from EMS.SPEAKER where name='顾康生';

I noticed that teiid-command.log file shows it as '顾康生' instead of '顾康生' results in retrieving 0 records instead of matching correct records.

Actual Issue

The SQuirrel SQL tool is sending the SQL statement with where clause 顾康生 or N'顾康生' to EDS correctly as shown below.
