Color Text Edit: does not respect Alt Gr + key characters

I tested the examples for some core functionality in the text editor, these are my results. Since every feature that I tested works somewhere I guess the intended behavior is to have it all working everywhere. Alt Gr + key is important for characters such as {} or @. ### In the sdl example: - [X] shift select - [X] ctrl + ←/→ for word movement - [X] sift + ctrl for word selection - [X] copy paste - [ ] characters with Alt Gr + key - [ ] characters with Alt Gr + Shift + key ### In the glfw example: - [X] shift select - [X] ctrl + ←/→ for word movement - [X] sift + ctrl for word selection - [X] copy paste - [ ] characters with Alt Gr + key - [ ] characters with Alt Gr + Shift + key ### In ebiten example - [ ] shift select - [ ] ctrl + ←/→ for word movement - [ ] sift + ctrl for word selection - [ ] copy paste - [X] characters with Alt Gr + key - [x] characters with Alt Gr + Shift + key PS. I tested on Linux.
