Will the tool support non western character such as Chinese in the near future?
The tools has made with Godot Engine and they support some more advanced font (chinese, Arabic). Made see how to setup a dynamic font for different languages but I never done such thing and don't know witch font could be the best since I don't know chinese. But, Here the souce code https://github.com/Levrault/LE-dialogue-editor, maybe you could check how to edit the font of the app to support every language you want
