Text filter exporting text as square symbols

Shotcut version 18.06.02 exports text created with the text filter as square symbols (see screenshots). This happens in both the x64 and 32bit version. GPU effects is disabled. What am I missing?

Works for me.

Is it possible you don’t have the font you attempted to use not installed on your computer?

This has happened to other people:

It would be nice to figure out what causes this.

I tried Arial and Verdana both to the same effect. I tried it on three different machines. One Windows 7 and two Windows 10. I thought it may be a language problem since they all run the German version of Windows but the Fonts folder is the same regardless of language C:\Windows\Fonts
