I guess I'm confused about why US keymapping is needed to enter the
LUKS passphrase during boot. The keymappings need to be the same for
luksFormat (used by the installer) and luksOpen (used by plymouth
during startup). I'm used to see a hint what that keymapping is
supposed to be, but I haven't done a non-US English installation
recently enough to remember the details :\

But what I can say is neither LUKS1 or 2 have a specific way to
indicate the keymapping. Hence dmcrypt/crypsetup folks recommend
modhex or base16 or even just the lowercase printable ASCII plus
numerals (no special characters). That way you don't end up getting
stuck with a passphrase using characters that a keyboard doesn't
support. Or alternatively you use UTF8 based passphrase with Finnish
keyboard in one keyslot and add another password in a second keyslot
that follows the recommendation, e.g. modhex based passphrase.
