Thanks for replying…
I think the font arial and other fonts like Google Noto fonts… are sopporting Both English and Arabic charachters… and please try doing so on any other writier program like MS Word…
I believe the problem is Gravit Designer render the whole text box character in a different mechanism, not like other softwere.
What do you suggest is manually making two separated boxes is not usable and not easy to do so, we usually write both Enlish and Arabic on the same lines
