Public bug reported:
I'm testing TPM/FDE with passphrase encryption on 26.04 (shipping with
plymouth 24.004.60+git20250831.4a3c171d-0ubuntu8). I'm using the
standard German keyboard layout for this test and set up the passphrase
'pässwörd' in the security center. After rebooting plymouth asks for the
passphrase and the keyboard layout is correctly set to German. However
the umlauts in the passphrase are not rendered correctly and the
passphrase is rejected, so I can only login with the recovery key. ASCII
characters that are located in different places compared to the US
layout work fine, though ('-' needed for the recovery key is located at
the position of the '/' in the US layout, passphrases containing 'y' or
'z', which are interchanged in the German layout, work fine too).
