I am struggling to generate report with Unicode fonts. The report is showing properly when I am previewing in designer. But when I am viewing it in a perspective session with report viewer, it is not displaying properly. My setup is a test environment where Ignition Gateway, Designer and Report Viewer are all running in the same machine.
I have tried the solution you mentioned but not working in my case. The reporting module not treating the "u" as a command rather as a character to print.
One interesting findings: when I schedule the report and generate in any format other PDF, it is working properly. It is only creating problem when generating report in PDF format.
