Ctrl + [ won't work on any non-English keyboard as the square parenthesis are hidden behind a modifier already. This is a constant problem with software, and now hardware, manufacturers that they assume everyone in the whole wide world is using a US keyboard.
Yes, you can remap and fiddle to make it work but that isn't the point, the point is to pay the same price, sometimes more than Americans and get the same value and experience. Instead we get an inferior experience that requires hacks. Not good at all.
Here in Norway I have never once seen a non-Scandinavian layout keyboard. Not once. As I'm from the UK I have considered getting a UK or US keyboard for coding at home, but at work it isn't an option, mostly because we all have standard equipment and because ø,æ & å.
The actual keyboard language is irrelevant since the layout is defined in software. You can just change the layout to US or UK and learn to touch type it. The US layout is lot nicer if you write a lot of code in my opinion.
You can also set up multiple layouts and switch via OS shortcut when needed.
