Non english Character's invalid display

Hello there
When i am reading a text in other than english from Fibaro quickapp (on change of that text)
the text is displayed incorrectly. The characters are unreadable.
However when I restart the HR then they get fixed.
Is there something i can do about this?

That makes no sense. I’m not sure why it would do that. Are you having this problem only in the Designer Simulator? Or do the actual apps themselves also have the problem?
