Hi, I'm playing in French on Linux under X11 with an azerty (fr latin9) keymap,
and I am unable to type “Ê”: it requires two keypresses (dead key on the right of “P”, then “E”), and for some reason that doesn't register.
I did played through on "KDE neon" linux with the default English + qwerty, everything worked well.
After finishing the game I checked from curiosity the options menu, and tried the Czech language (for menu+story), and the options menu went crazy. After that the things shown in options are no more in sync with game behaviour, like the first language was shown as "japanese", and keyboard layout some different, and I was not able to change anything except that menu+story language, which looks to be the main option any way.
After setting it back to American English and restarting game the options menu looks ok.
Not a problem for me, as I'm used to write even in Czech without accents, and the game wants me to write properly, so I would be probably undecipherable for the auto-adjust algorithm (as I can type around 30 words per minute in English or Czech without accents, but with accents I'm down to about 3-4 words per minute), and I understand English well enough to enjoy the story.
JFYI that the linux binary looks to have some bugs in the settings/localization parts.
Everything else worked great, only one crash when loading the main map after finishing one sub-map, but it did work correctly after reload and save was correct too.
