Filter in chinese language is not respecting in Cognos 11

[xyz]

Hi All,

I observed a strange behavior, we are using Cognos 11 and database is Oracle. The database has data in Chinese language. We have data for some Chinese description text filed in database, when I try to drag a filter in detail filter section with the value present in database, report is giving 'No Data Available' message. But, we have location field which has values in English text, but when I filter on the Location field is working. Just wondering, where am I doing wrong?

Tried changing the content language and tried to apply filter, this also didn't work.

Can you please let me know your suggestions/idea/missing piece.

Thanks in advance.

Thanks & Regards,
XYZ
