It looks like you have to check all languages that are possible.
You may narrow it down by looking at what could have happen and
by looking at the characters in your passphrase. For example if
you have, say, 12 characters and 9 of them are the same on most
keymaps, then you could try a direct brute force.

It could, but iot looks like you have to write it yourself.

The other option is that you mistyped on creation. One reason
to allways test the passphrase afterwards before doing anything
with the crypto-container.

If this is LUKS, then if it asks you for a passphrase,
they should be fine. If is is plain dm-crypt, then there
are no headers that could be corrupt.

It all depends on what you did wrong.

I gahther this is a new installation and you would only lose
a few hours of configuration work, correct?
I think in that case, doing it again and this time testing the
password at your earliest oportunity would be the best option.
For an encrypted boot, it may also be highly advisable to thest
whether you can decrypt it witha life-cd or unencrypted recovery
