Reading a line from stdin does not need elevated powers. Drop the sudo.

ISO8859-1 or ISO8859-15 encoding. Euro mutated to "e".

UTF-8 (unicode) encoding. Euro mutated to "e".

ISO8859-15 encoding. Correct euro hex code (a4).

dumpkeys saves text console mappings. It should not matter whether you run
it from console or X windows.

So you ended up using mutated "e" for euro symbol.

Yes. Avoid using euro symbol in passphrases.

Summary:
1) Knoppix text console in ASCII mode mutates euro symbol to "e".
2) Knoppix text console in UTF-8 mode mutates euro symbol to "e".
3) Knoppix X windows uses true ISO8859-15 encoding for euro symbol.
4) SUSE text console in UTF-8 mode mutates euro symbol to unicode "¤".
5) SUSE X windows uses true UTF-8 unicode encoding for euro symbol.

You should be able to decrypt your key file on any working setup that is
using ISO8859-1 or ISO8859-15 encoding, but instead of typing euro symbols
to your passphrase, you need to type e in place of euro.

For SUSE text console, you should be able to decrypt your key file using
these commands:

    kbd_mode -a
    loadkeys /boot/usb/default.kmap
    gpg --decrypt </boot/usb/rootkey.gpg

Where /boot/usb/default.kmap is that strange keyboard layout from Knoppix.
