An issue according to supporting Arabic language in Combined Images feature in Snagit 2019

As a first look to one of a new great feature of Snagit 2019 , which is Combined multiple images in One, I see that Arabic language is not supported to view in the combined images so that the result is a serious of a question marks instead of Arabic words for both Caption and Title fields , so I ask if there is an ability to add a new Plugin to access this issue
