I am using a Danish keyboard.

When I first tried to use my old key (that work in previous Fallout series and also in Skyrim) , the one above Tab, to open the developer console, nothing happened.

So I tried all other keys on the keyboard but still no luck. After I tried and when used the "Æ" above "." the console opened.

This might happen to others using non English keyboards so here it is a solution/work around for the problem.






Update

The Fallout 4 Wiki as published most of these settings



There are more in the discussion area, have a look there if you can't find a suitable solution on this page.

There are other keys that work without needing to use this mod. See below.


This mod can still be used for convenience OFC, so you don't have to remember an extra key and have it where it used to be in previous games.

Turns out that on Danish keyboards you just need to use the "æ" key  and the console will open.

Let me know what keys work with other languages so I can Update it here and people can find the solution right away.

Requirements (only if you want to bind to another key)

You will need to install AutoHothKey 


Instructions

It's a AutoHothKey script that changes the "½" (in my case) to "Æ".

The script is very simple so you can adapt it to your situation. 

Just replace the the "½" (or your key of choice) and "Æ" to  whatever keys your keyboard uses.

Use Notepad or other Text editor, make sure to save it with the extension ".ahk".
Save it on your desktop or any other place you like.
Double click it so it runs Autohokkey before launching the game.
It will be on your System tray with green Autohotkey symbol/icon.

After finishing the game you can just right click the icon and choose exit so your keyboard layout is back to normal.

 

 On a 101-key US keyboard this is not a problem, the tilde key is located just above the TAB key.  US Keyboard Layout below.



 
 The correct key used to be the one that has the ½ and § symbols on it. Danish Keyboard Layout below.



 
In Skyrim or Fallout 3/NV The console could be accessed in-game by toggling the 'tilde key' (the actual key could be ~, º, ¬, |,^, \, §, ², etc.. depending on your keyboard layout), found near the "1" and "Esc" keys on most keyboards. 




Other solutions:

Binding it to F12 or other key of your choice

___________________________________________

; Map grave accent/tilde key (`/~)
F12::SendEvent {vkC0sc029}
+F12::SendEvent +{vkC0sc029}



; On some systems you may need to use the less optimal mapping (this is the one I am using with "½" and you can download here)
F12::~
