The recent news article about Godot 4.0 budgeting's top topic was RTL font support. I just wanted to add that it would be very nice to also consider vertical text flow for languages such as Chinese and Japanese (top-to-bottom, right to left).
Many thanks to all the contributors and donors who supported Godot!
If that's the case, then it would be a good idea to make a feature proposal here. https://github.com/godotengine/godot-proposals/issues?q=is%3Aopen+is%3Aissue
Is vertical text flow just about having one character per line, or does it involve something more complex?
If it is, you could split a string to add \n between each character and display it in a Label or RichTextLabel.
