Added Input Method Editor (IME) suppport

### Feature Description

I just found this project and I am really liking it, thanks for the work putting this together.

One thing I didn't find in the features or the issue tracker was support for IME which is important for being able to switch keyboards to input language that use other scripts like Japanese, Chinese, and Korean.
Having one setup and integrated out of the box would be fantastic.

The issue names no files, tests, or entry points. Start by clarifying the intended IME setup and compositor scope with maintainers; done would mean integrated IME support for Japanese, Chinese, and Korean input across all compositors.
