[WD20] - Cannot Export Reports with UNICODE text in PDF

Hello,

I have configured a project for UNICODE
[attachment 2585 2018-02-22_115510.jpg]

I have set all the Text Fields in all files in the Database to store UNOCODE
[attachment 2586 2018-02-22_115720.jpg]

I have designed reports that are showing the UNICODE text on screen but when we export them to PDF the resulting PDF when opened in a PDF viewer like Acrobat Reader and Foxit PDF Reader comes up with Question Marks (?).

Why must this be happening?

How to solve this problem?

TIA
