Unless otherwise specified in the question the rule source should be considered English as this is an English based website. However that being said when the rules where thrown into Google translate they can out very similar to the English versions.
As for your examples from what I can see they seem the same in each language though I didn't see the restriction on districts in the Dutch version I did see it int he German version.

Building Districts
A character has made it known begins his
Turn:
• Income: He takes 2 gold pieces
or
he takes 2 building cards from the deck,
selects one of them and takes them into your hand. The
he puts another card on the discard pile.
• building action: Then he must 1 building card from the
Lend a hand in front of him on the table and continue to build his own city.
He pays the specified number of gold pieces on the map
in the middle of the table.
Note: Each building must designed in a city only once
be. It may therefore e.g. in a town already has a
Taverne is no more tavern are designed.
• Character Action: At any time during his turn, he may
use his character property. This means that
you have to choose a time when
alternating his property (see also examples on
End of the description of the character cards).
With 2 or 3 players, each player has 2 characters and is therefore
2 times per lap on the train. Players can use this tactic,
by about saving the receipts of the first character to
to build the next an expensive building
German - Expansion (Google Translated)
Immediately if a player builds the bell tower , he must decide whether the
Game after the 7th or 8th after the building is completed. If the
Bell tower destroyed, always played until 8 building
(This rule says the original end condition is restored if the bell tower is removed not that the game doesn't end if the bell tower is removed after the 7th district is completed and 7 is the current winning conditions)
English - Bell Tower Card Text
When you place the Bell Tower in your city, you may announce that the game will end after the round in which a player first places his 7th district. You may do this even if the Bell Tower is your 7th district. If the Bell Tower is later destroyed, the game end conditions return to normal
From what I can tell in the case of the bell tower the rules are the same in all 3 languages its just how people see them after translation is different.
