A minor correction after playing with it more: the keyboard layout is "respected", in that after switching keyboards I have a Japanese qwerty layout. Something in trinity seems to be interacting poorly with (I don't know the proper term for this) the non-committal typing? When inputting Japanese you type in qwerty and the input method "suggests" completions. a -> the hiragana for a -> various kanji that it could be, for example. That completion isn't occurring on discord, though it does seem to occur everywhere else.
