As mentioned in the post above, what constitutes as European is decided by the European Council and European Commission. You are correct in that it is a requirement but there is nothing stopping them from going "Canada is European, as it shares our values, ideals, and ideologies". The decision does not have to be geographical.
It's unlikely and kind of a "the rules don't say a dog can't play basketball" type move but it's technically valid.

Seems like the game lacks detection for spamming the same letters. If you find out a yellow letter you can keep putting more than one instance of it into the word even if the solution tells you that it does not have more than one instance of that letter in the word since there is no "cannot contain more than one X". You do of course risk accidentally turning the letter red in the process but it gets you a guaranteed way to ensure an incorrect guess.
