This PR has gotten a long time to cook on, tested on MacOSX (by my self), Windows (with some defects do to SDL implementation as reported by Guldo on discord) and Linux on desktop environments that support it. Lets merge it so users that have a real need for this can test it and in return we get back some real feedback. we can always do new point base releases to fix stuff that may come up and not catch by us.

I wanted to test this but I cannot trigger the IME entry. Original PR mentioned "ctrl+shif+u" and "ctrl+." and it didn't work on XFCE Linux. Where are these shortcuts specified? Do I need something additional installed?

Those shortcuts are likely implemented by IBus, so you might need to install it if you want to test those.
(AFAIK GTK applications have a fallback in case IBus is missing, so those shortcuts may work in GTK apps.)

IMEs are usually more for entering text in languages that need composition (like Japanese), so you'd need to install an Input Method Framework (like fcitx5, IBus or SCIM), then an actual IME compatible with that framework. See the Arch Linux wiki article.

You might also need to install fonts compatible with said language, for example NotoSansJP, and add it to a fontgroup in Lite XL to be able to actually see what you're writing.

• Download NotoSansJP regular from https://fonts.google.com/noto/specimen/Noto+Sans+JP
• Move it to ~/.config/lite-xl/fonts
• In your user module add

local code_font = renderer.font.load(DATADIR .. "/fonts/JetBrainsMono-Regular.ttf", 15 * SCALE)
local jp_font = renderer.font.load(USERDIR .. "/fonts/NotoSansJP-Regular.otf", 15 * SCALE)
style.code_font = renderer.font.group({code_font, jp_font})

Let me know if you need more precise instructions.
