Configuration:
- Web browser and its version: Chrome
- Operating system and its version: Microsoft

What is the expected behavior? 
Embedded PDF Viewer should display right font with all characters

What went wrong?

Is it possible to add some other font? Is it possible to manage what encodings will be used?

Thank you in advantage
