I agree that the engine should allow users to change font. May be it should refer to system fonts instead of having to bundle font files with the engine or have to specify the font file path in the configuration.
However, … I think having Thai fonts in the engine’s editor is more urgent and wouldn’t take as much time. Having to replace the font file manually, or have to manually compile the engine is not really healthy for us Thai. I mean if Epic really into virtual production then having more language support on the UI would bring more people into the Unreal ecosystem.
It’s kinda silly, when one engine have Thai font render in the text field but it cannot properly display it, while another one is totally capable but it does not do that. Yes the Unity 3D’s situation is much worse than Unreal, but we shouldn’t discuss that here I think
