Non-english characters overlapping in PDF forms


I made a PDF form in Draw which is being programmatically filled. However, when entering non-english characters, they
are mostly overlapping (see attached image). This behavior isn’t omnipresent, it works fine on my PC, but those
problems do happen on the server where the app is deployed. I’ve tried setting different fonts for the fields in the
forms designer but it hasn’t helped. Would anyone have any idea what might be causing this?

Thank you!

The first thought: does the server have required fonts?

Yeah, I’ve tried with Arial, Calibri, and Open Sans. All are present on the server
