Hi, I am using Ganntproject now for a number of years. Very happy with it sofar.
Today I suddenly see unreadable characters in my projects. I have updated Java runtime, started my iMac again but no solution. Also no solution after downloading the latest version of Ganttproject.
Can you please advice how to solve this issue?

Please share the project file, if you see them in the project data.
Looks nice 
Did you change application font by any chance?
You can try removing file .ganttproject from your home directory. It is the place where GanttProject keeps all settings, including application font. Other way to change it is using Edit > Settings > Application UI but it is going to be fun with such fonts
No, I didn’t change the font. And, of course, changing settings is now undoable. Can it be that the issue is caused by the fact that I am now using MAC OS Sierra (latest OS version), and that the current version of Ganttproject is not yet aligned to this version?
and there we are. Somehow I managed to change the fonts… thnx for your support!
