Or at least keys or key combinations for the stuff you need, which might 
differ e. g. with the country you live in. There are countries which 
have keyboards with äöüß, others with èàéî, and so on.

So what? If I type Shift-3 here, I get a § (U+00A7). And the ° (U+00B0) 
comes with Shift-^, the µ (U+00B5) with AltGr-M and the € sign with AltGr+E.

And if I had a useful OS here at work, I even could use the compose key 
to produce many other non-ASCII characters. To be able to create each 
and every of them is not needed in order to have support for them in a 
language, just the needed ones.

Useful editors use them as well, although you have not all of them on 
your keyboard.
