So I have a stimulsoft report that is working on SS Ultimate 2014.3 designer. However, when I tried to run the report with SS Ultimate 2019.2.3, I get the error below:

I was able to determine that the cause of the error was when my queries were trying to concatenate chinese characters, sample:
SELECT CONCAT(YEAR(GETDATE()), N'年', MONTH(GETDATE()), N'月', DAY(GETDATE()), N'日')
and when my sql statements had chinese text in the WHERE clause, sample:
SELECT N'增加'
Am I missing something in SS thats causing this error? Also, I'm connecting to one single database when running the report between the two SS versions mentioned above.
Thank You.
