EOS/KDE — Which IMF/IME does/can it use?

These past 13 years or so, I’ve been using uim on Linux Mint, and happily use ibus on EOS/Cinnamon.

I’m thinking of giving EOS/KDE a trial spin, what IMF/IME does it use on a fresh install (or can it use)?

I don’t need fancy stuff or CJK input, just the following is mandatory:

  • Unicode input via Ctrl+Shift+u.
  • Possibly, emoji input via Super+. or Super+:.
  • My lengthy .XCompose working correctly.
  • Ideally, not breaking Espanso (cross-platform text expander).
  • All above must work in the terminal, too.

I’m a little unsure here, since ibus is rather integrated with GNOME, xim never really completely worked for me (on Mint), and people are saying KDE would prefer Fcitx

I’m typically using the German deadtilde keyboard layout plus a few modifications like nbsp on 2nd level, Compose on Caps Lock, Unicode arrows/math on num block, etc.

Old man, finger memory, and lots of European languages to write, you know… Before I came to Linux full-time, I even made a Writer’s Keyboard for Windows (still used by some professional authors, but some bad design decisions, in retrospect—wish I had known the Linux kbd layout back then).
