... I use special characters for my passphrase, which should be a good idea for a passphrase, and grub2 uses a different keyboard layout than the Linux installation. By that I need to type two different passphrases.
see "Some side notes for the fun of weirdness" and therein in particular "Use non-ASCII characters in usernames and passwords to lock yourself out" in https://en.opensuse.org/SDB:Plain_Text_versus_Locale What makes a passphrase good is first and foremost length. Length is more important than the size of the character set because the formula is number_of_words = size_of_character_set ^ word_length e.g. with only 36 ASCII lowercase alnums (i.e. 0-9 and a-z) versus all 95 printable ASCII characters it is e.g. 36 ^ 13 > 95 ^ 10 so that a passphrase with 13 ASCII lowercase alnums is better than a passphrase with 10 printable ASCII characters and in the same way is e.g. 36 ^ 17 > 95 ^ 13 so that a passphrase with 17 ASCII lowercase alnums is better than a passphrase with 13 printable ASCII characters and so on...
